Just for fun here, because I don't have an answer, because I am too lazy to figure it out. 

I just donated enough golf balls that pretty much filled up two, 100 gallon barrels, to a local driving range. The number "100 gal." was stenciled on the barrels, so I am just assuming. There was about an inch cut off the top of the barrels. 

So how many balls would fill up those two barrels?

It was either donate them to the golf course, or put them in the local land fill. The resident pro says I can have a bucket of balls anytime I want. Just need to see him. Told him I might buy a few lessons myself as thanks for taking the balls off my hands. My storage room is now empty.

Ballpark guestimate about 12,000 balls.  I can't say I've seen 100 gal barrels, most that I see are 55 gal.  Even so, thats a whole lot of golf balls.  Can I ask, how did you load and transport those barrels?

So...you gave him "Both Barrels" and he gives you range privileges. Nice!

I'm not an engineer.  But I'd estimate that you're talking over 15,500 balls.

I arrive at that via:

There are 23,100 cubic inches in 100 us liquid gallons.  A golf ball is 2.5 cubic inches.  That gives 9,240 units per 100 gallons - but I'm lopping off ~10% of the volume for space (not dealing with liquid) - giving me ~8,200 per barrel, then a little more for the top of the barrel being cut, giving us 15,500+.

I always lose the "how many candies are in the jar" contest at our office, though, so take it FWIW. ;-)

How in the world did you a.) collect & store 15,500+ golf balls, and b.) transport 15,500+ golf balls. 

Addendum:  I agree w/Dave; I've seen 55gal barrels.  But a 100gal is one huge-ass barrel!

There you go, I'd say we have some upper and lower bounds.  I estimated based on a cube, 1.68 inches on a side, which I know is too MUCH volume for a ball.  A sphere 1.68 inches diameter is to small a volume, because there's always "pore space".  I could go to some reference somewhere and find the porosity (percentage of pore volume) given the most dense arrangement of uniform spheres, but I'm way too lazy.  Simple to say its a S___-load of balls, that's gotta weight 500 pounds or more per barrel.

Googled 100 gallon barrel dimensions and found one that claims to be 27x27x46 inches.  Asssuming that to be accurate, and then roughly assuming that a golf ball consumes 1.5x1.5x1.5 cubed volume of space, then that yields almost 10k balls.

So, I guess my rough guess will be up near 19k balls.

OK, I'm not too lazy.  1 US gallon is 231 cubic inches, so 100 gal is 23,100 cubic inches.  Minimum porosity is 25.95 %, so the most dense arrangement of balls in 100 gallons would have 5,994 CI of void space, leaving 17,105 CI for golf balls.  A 1.68" diameter sphere has a volume of 2.5 CI.  That means you can get 9,314 golf balls in 100 gallons, neglecting edge effects.

Yeah, I didn't really feel like trying to get too into it so I figured a cube but went slightly smaller on all sides to account for balls nestling into the crooks between adjacent balls.

I mean, that's how most of my "calculations" go anyway.  Estimate, estimate, estimate! (Then round up to the safe side) :)

That 25.95% assumes you've carefully packed each layer, arranging them perfectly for maximum efficiency. For "random" packing, that number is closer to 35%.

So, closer to 7,000 balls, practically speaking.

5 gallon bucket holds about 300 golf balls, so I'd say around 6,000 golf balls per 100 gallon barrel, 12,000 total for 2 barrels.

This approach would have to take into account the surface affect (balls against the edge of the barrel having different spacing versus the balls away from the surface). The affect of the surface goes down with larger volume.

I would have weighed the empty barrels to tare them, then weighed the full barrels. The using an average weight of the balls from 10 to 100 balls, we could estimate the total number of balls.

One of the businesses I work at a long time ago cleaned up properties that use to be old golf courses. Thats where most of them came from. Others came from areas next to driving ranges that were cleared for single, and multi family homes. Others, I just accumulated over the years. .

As for storage, they were kept in plastic crates. Most were stored in two staorage units, with other junk. A few hundred or so were in my garage. I have a cousin who lives on a golf course, who use to give about 4 or 5 , 6 gallon paint buckets of balls every  year that they collected from their back yard. 

The hardest part about moving them was the plastic crates they were originally in, cracked open when we went to move them.  We put them in other containers, and loaded them into a rental truck. Each crate was off loaded by hand, at the course,  and dumped into the larger barrels. I hired my grandson and a couple of his friends to help move them. 

Now the "why" part. A long time ago, myself and a couple of friends had this idea to open a driving range on a piece of property we all owned. We figured since were collecting the balls, why not use them. That idea fell through for various reasons. Next I dea was to sell them to some company in Arizona who baught used golf equipment, including balls. That idea went south for what ever reasons too. So for the last 9 years or so, these balls ( and other stuff)  have just been stored, mostly forgotten about. A few months back, my two friends and I decided to clean out our storage units with some 20 years of "business stuff" stored in them. Nothing really sinister or anything. Just cleaning up stuff. 

Based on what you all have calculated, I figure 10K plus is about right. I don't actually know if the barrels would hold 100 gallons, because I dont really. know how much of the top was cut off. I just know they won't need to buy any balls for a while at the range.

    • Day 610 - 2026-06-03 Got some work in between lessons today. Rare late day, teaching until 7:30pm.
    • Let's continue on… Cool. The thing is, nobody's claiming par is "reliable" and par's inclusion piggy-backs in the course rating, which is awfully close to par and, thus, brings par in to make it make sense. Once again, for those in the back… (CR - Par) just makes it really easy to know what kind of score you need to shoot to best, match, or play worse than your handicap index. Yes, when par is different, the players from the higher par tees get an extra stroke (72 vs. 71, the 72s get an extra stroke. That makes sense and is a small complication (more info at https://www.usga.org/content/usga/home-page/handicapping/roh/Content/rules/Committee%20Content/USGA/LG_R6d.htm). However, most of the time, this adjustment will not be needed, as many courses play to the same par for the same genders from all sets of tees. And, the rare times it is needed, par (measured in whole numbers, integers) and strokes (also whole numbers/integers) map easily and the idea is easily grasped. Dean seems to be unaware of the fact that most every golfer carries something orders of magnitude more powerful than the highest end desktop computers available the last time he consulted with the USGA in their pockets. While it is quaint that his club puts printouts by the first tee… get with the times, Dean. Look up your handicap index and course handicap in the GHIN app and get on with it. It's a better system than the one that didn't account — at all — for a difference in the playing conditions (via an algorithm, not a judgment). Dean's assertions about the "less precise system because of par" continues to make absolutely zero sense. Right, it still changed tee to tee. Now it just changes differently… and in a way that more accurately reflects the score you need to shoot to play to your handicap. Previously, a 1.1 index would get 1 stroke on a 66.7/122 par-72 course. Now they give four strokes back to the course and must shoot 68 to play to their handicap. This makes way more sense. The 18-shot difference is a pretty extreme example. Maybe a long course that also offers a par-three set of tees could play that long, but… man, that's not going to be super common. Sensationalistic much, Dean? Also, once those unhappy (complete assumption) golfers realize a) what the change shows them (playing to net par = playing to your index) and b) realizes that their differential is going to be the same… I think they'll get over their initial questions. No. And yet… if he shoots the same scores, he'll get the same handicap index he has now. But he'll know on each course what score he needs to shoot to "play to his handicap." Sheesh, Dean. This stuff isn't that hard to figure out. Enough with the sensationalistic stuff. I don't find it "unacceptable" at all. Then again, I'm not nearly 80 and seemingly incapable of doing basic math these days. No. This literally makes no sense, as that part of the differential calculation and the course handicap calculation remains identical. Good! No. Categorically wrong. They should have been adjusting their handicaps all along. Previously it was by subtracting the course ratings. Which… is still basically what's done, with the addition of the course rating being "baked in" to the course handicap calculation. Dean is wrong here, or doing some math heretofore unknown by the world. When par is the same, what determines the difference in handicaps? The course rating, which Dean loves! Sheesh! You had to things when players were in situations like this before, too. This is getting exhausting. He keeps using words like "less precise" and "unfair" but does not seem to understand what they mean. This is like the Princess Bride meme: "you keep using that word. I do not think it means what you think it means." The caps reduce upward movement. Committees have reign to reduce a player's handicap, and there's still an automatic Exceptional Score Reduction. I'm going through these more quickly now because… well, it's silly how badly Dean misses the mark with this blog post. Dean is literally confusing the upward movement (with the soft and hard caps) here with the exceptional score reduction which is used when lowering handicaps due to an exceptionally good score. The creators of the WHS are handicap experts. They know more about the current state of handicaps/handicapping than the Pope Emeritus. It's been shown to have almost no effect across all handicaps. Yes, some 36s under the old system are now 35s under the new system. Yawn. He should have stopped there. It's easier to apply and makes more sense. This makes no sense. It's "not complex" but players will have to guess? And, for men or women, the stroke index of each hole doesn't change because they play a different set of tees. They get a different number of strokes, but it's always been true that when you get 14 strokes you apply a stroke to stroke index holes 1-14, and when you get 11, to just holes with a SI of 1-11. Objection, your honor. Assumes facts not in evidence. Dean's just out here continuing to make shit up about "the inaccuracy of par" and ignoring that with Par (an integer) came the Course Rating, which he agrees is precise and accurate. No. No, this is inaccurate. Also, as noted, you can randomly assign stroke indexes, and so long as all the low numbers or all the high numbers are not clumped together at the beginning or ends of the 18 holes, matches generally work out the same. This is inaccurate. It is an algorithm that looks at scores. That's it. Also, this is better than a system like the prior one where no such thing existed at all. Wildly inaccurate and off-base. Did they do actual testing? No need. They have millions and millions of rounds and ran many, many, many simulations. That's testing. Dean seems to continue to be unaware of the fact that computers are more powerful now than they were in 2002. But, he's nearly 80, so we can understand if not going so far as to give him a pass on how much he gets wrong. Cool. Noted. For the most part that was because many countries haven't been able to rate enough of their courses. :sigh:
    • Day 3 (3 Jun 26) - More work on keeping arms connected today - hard foam balls with 7i and 5w…..
    • Day 274 6-3 flow drill getting chest through, arms in front. Arms get a little pinned to the side, not as much in front as I want them when I add speed. 
    • Shot 48 yesterday.  For me bogey golf is good.  I was 10 over through 7 and figured with a Par 3 and 4 coming on all I needed was birdie / par to get my 45. I had a great tee shot on #8 and sunk  a 5 footer for birdie, game was coming together, now just needed par on #9. Had a great tee drive and the green was within range for a hoped GIR or nGIR.  But I pulled the shot left into tall weeds and needed to take a drop.  So much for par, but a bogey for 46 is still good for me. I hit my lob wedge to get over a small tree and saw the ball riding nicely  on line to the pin when my club hit the ball a 2nd time on my follow through causing the ball to change directions and ended up @ pin high but along the same tall weeds I just took an unplayable out of.  had no room for a backswing, Just hacked at it and it shot across the green to the rough on the far side.  Needed a chip & 1 putt got a triple bogey. you can see the hole fall apart in the screenshot below.
