When this conversion is useful

A US liquid gallon is smaller than an imperial gallon. Confirm which gallon a vehicle, tank, or product specification uses before converting.

Accuracy and rounding

The US liquid-gallon definition is exact. Container capacity and fuel readings may have their own tolerances, so round accordingly.

Standards references

CalUnit checks physical unit relationships against authoritative measurement references. See the NIST Guide to the SI conversion factors and the BIPM SI Brochure. Regional cooking measures and digital storage conventions are identified separately because their names can represent more than one definition.
