Kilograms of Liquefied Natural Gas to Gallons Calculator
This tool applies only to LNG in its liquid phase under cryogenic conditions.
Enter the liquid mass in kilograms.
LNG density must come from the cryogenic liquid state.
LNG density must come from the cryogenic liquid state.
Only the liquid phase is valid.
LNG must be measured as a liquid, not as gaseous natural gas.
Formula
US gallons = kilograms ÷ density in kg/L ÷ 3.785411784. UK gallons = kilograms ÷ density in kg/L ÷ 4.54609.

Liquid butane must be measured in its liquid phase because temperature and pressure change the volume relationship.
Diesel density varies by fuel grade and biodiesel blend, so the conversion should remain approximate.
