How it works
Volume equals mass divided by density. Divide the kilograms by the liquid's density (kg per litre) to get litres, then convert litres to US gallons.
litres = kg ÷ density(kg/L)
US gallons = litres ÷ 3.78541
US gallons = litres ÷ 3.78541
Worked example
10 kg of water is 10 ÷ 1.0 = 10 litres, which is 10 ÷ 3.78541 = 2.64 US gallons.
