Kilograms of Cooking Oil to Gallons Calculator
Cooking oils are generally less dense than water, so equal mass converts to a slightly larger volume.
Oil grades and temperature shift density.

Cooking oil FAQs
How many gallons is 1 kilogram of cooking oil?
Use the displayed density to estimate the volume.
Is cooking oil lighter than water?
Yes, most cooking oils are less dense.
Do different oils have different densities?
Yes, blends and grades vary.
Can I use used frying oil?
Yes, but only as an estimate.
Why does oil occupy more volume?
Because it is generally less dense than water.
