A general formula:

mass (kg) = density (kg/m3) × volume (m3)

weight at sea level (lbs) = mass (kg) × 2.20462262

Volumes, 5 gallons:

5 US dry gallons = 0.02202442 m3

5 US liquid gallons = 0.01892706 m3

5 UK gallons = 0.02273045 m3

"5 gallon" bucket (15" h. x 12" w.) = 0.02780000 m3, to rim

Densities, approximate:

loose dry sand ≈ 1442 kg/m3

dry sand ≈ 1602 kg/m3

wet sand ≈ 1922 kg/m3

quartz sand ≈ 1201 kg/m3

Choose the appropriate volume and density for your application and apply the general formula.

m = d × v

w = m × 2.20462262

For a typical "5 gallon" bucket, which holds 6.3 US dry / 7.3 US liq. / 6.1 UK gallons to the rim, filled with loose dry sand, you get:

1442 kg/m3 × 0.0278 m3 ≈ 40.09 kg

40.09 kg × 2.20462 ≈ 88.4 lbs

Some solutions for loose dry sand:

"5 gal." bucket: ~ 88.4 lbs

5 US dry gal.: ~ 70.0 lbs

5 US liq. gal.: ~ 60.2 lbs

5 UK gal.: ~ 72.3 lbs
