How much does 140 gallons of water weigh?

Answer 1

144 g

This is because 1 mL (milliliter) of water has a mass of 1 g (gram).

Strictly, this is only exactly true at 4° Celsius. At temperatures higher or lower than this, water expands and has a lower density, and therefore weighs less.

But the difference is small. For example, at 20° C the density of water is 99.8 per cent of its density at 4° C.

Answer 2

140 gallons of water weigh approximately 1,167 pounds.

Answer 3

1120 pounds

Answer 4

9 lbs
