Volume units need jurisdiction awareness. US customary gallons and fluid ounces are not the same as UK imperial units, so the converter keeps those unit identities separate instead of treating “gallon” or “ounce” as universal.
The interactive calculator, reference table and indexed pair pages all read from the same conversion registry, so unit definitions and formulas stay synchronized.
