Reference

How volume conversion works

Volume measures three-dimensional capacity. US customary and Imperial liquid units have different sizes, so the unit system is always shown explicitly.

Values are converted to cubic meter first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Accuracy note: US liquid and Imperial gallon definitions are treated separately and use their exact legal values.
