How it works
Volume is where US and British units part ways. A US gallon is 3.785411784 L (231 cubic inches) while an imperial gallon is 4.54609 L, about 20% more; the same goes for pints and fluid ounces. The converter lists US customary, imperial and metric units in separate groups so you pick the right one for your source: a US recipe, a UK fuel-economy figure, a fridge rated in cubic feet or a water tank in cubic metres.
Cups deserve a note. The US customary cup is half a US pint, 236.59 mL; US nutrition labels use a rounded legal cup of 240 mL; Australia, New Zealand, Canada and many metric recipes use a 250 mL cup. Tablespoons are 14.79 mL (US) or 15 mL (metric). For converting cups of flour or sugar to grams, use the cups-to-grams converter, which accounts for each ingredient's density.
Factors come from the exact definitions of the inch and the imperial gallon; see NIST Special Publication 811 (Guide for the Use of the SI), Appendix B.
Common volume conversions
Volume has the most look-alike units: the US and imperial gallon, pint and fluid ounce all differ, and a US customary cup (236.6 mL), the US legal cup on food labels (240 mL) and a metric cup (250 mL) are three different sizes.
- 1 US gal = 3.785411784 L (L = US gal × 3.785411784)
- 1 imp gal = 4.54609 L (L = imp gal × 4.54609)
- 1 US cup = 236.5882365 mL (mL = US cup × 236.5882365)
- 1 US fl oz = 29.57352956 mL (mL = US fl oz × 29.5735295625)
- 1 US tbsp = 14.78676478 mL (mL = US tbsp × 14.7867647813)
- 1 ft³ = 28.31684659 L (L = ft³ × 28.316846592)
