how many gallons in my sump?

i was wondering how many gallons would be in a sump that was 21x10x15. is there a formula to figure that out?

Vital Statistics Johnny?

Capacity.

Length x Height x Width divided by 1728=cubic ft.
Cubic ft x 6.23=Imperial gallons.
Imperial gallons x 4.55=litres.
Imperial gallons x 1.20=US gallons.

LOL.

Wow imperial gallons! ;D
Sounds so regal.

LxWxH (inches)/231

Therefore, 21x10x15 / 231=13.6 gallons.
