How Much Does 5 Gallons of Sand Weigh?

I’m thinking about making some diy sand buckets, complete with Fat Gripz, as a conditioning tool. But that got me to wondering… How much would something like this actually weigh? Assuming that I use five gallon buckets, it’s actually pretty easy to figure this out.

A typical 50 lb bag of play sand (available from big box retailers for less than five bucks) contains ca. 1/2 cubic feet of sand. Five gallons corresponds to 0.67 cubic feet, so the math works out like this:

0.67 ft^3/bucket ÷ 0.5 ft^3/bag = 1.34 bags of sand per 5 gallons
1.34 bags/bucket x 50 lbs/bag = 67 lbs of sand per 5 gallons

Now, I know what you’re thinking. This isn’t a particularly high number for loaded carries. I agree, but… As noted above, I’ll be outfitting my buckets with Fat Gripz, which will significantly increase the strain on my grip. Plus, I plan on carrying them uphill.

As it turns out, our driveway has a roughly 100 foot stretch with a ca. 20% grade from the street to where it flattens out up near the garage. Between the increased grip demands and the incline, I’m thinking that a couple of buckets of sand could end up being a fairly effective conditioning tool.

P.S. It looks like pea gravel weighs a similar amount, with a 0.5 cubic foot bag weighing in at close to 50 lbs. YMMV.
