Results are estimates. Density varies with product and conditions. Use the official technical or safety data sheet where accuracy matters.
Water FAQs
How many gallons is 1 kilogram of water?
About 0.264 US gallons or 0.220 UK gallons at the standard density.
Does temperature change the result?
Yes, water density shifts slightly with temperature.
Is 1 kilogram of water the same as 1 litre?
It is approximately 1 litre at everyday conditions.
Why are US and UK gallons different?
They use different litre-per-gallon definitions.
Can I use this for storage estimates?
Yes, for quick planning estimates.

Salt water is denser than fresh water, so the same mass usually takes up a little less volume.
Milk density changes with fat content and processing, so whole, low-fat, and skim milk should be treated as approximate.
