How many gallons do you weigh if you are 110 pounds?

Answer 1

Gallons are a measure of volume, not weight. You can still get an answer if you know the density of the average human. Humans are only slightly denser than water. So let's assume a density of 1.01g/cm^3.

110 pounds is 49.895 kg, or 49,895 grams.

We divide this by 1.01 to get the number in cm^3, which gives us 49400.990 cm^3.

One gallon is 3785.412 cm^3.

To get gallons, we divide 49400.990/3785.412.

This gives us an answer of 13.050.

A 110 pound person would displace a little over 13 gallons of water.
