Frequently Asked Questions
What is the SI base unit of volume?
The SI base volume unit is L. Most conversions factor through it, except temperature which is affine and fuel-economy which is reciprocal.
Which unit systems are represented?
Volume includes both metric and imperial units (where they exist in this category). For mass and length, both metric (kg, m) and US customary (lb, ft) are listed. For temperature, the three most-common scales (Celsius, Fahrenheit, Kelvin) plus Rankine and Réaumur.
How accurate are these conversions?
Conversions use the standard SI factors (NIST values where applicable). Where two slightly different definitions exist (e.g. KB vs KiB, US vs UK gallon), they are listed as separate units rather than auto-rounded.
