About the liter and the US cup
The liter
The liter (L) is a metric unit of volume defined as exactly one cubic decimeter (1 dm³). Although not an SI base unit (the SI unit of volume is the cubic meter), it is the most common metric volume unit in everyday life, used for beverages, fuel, and chemistry. One liter of pure water at 4 °C weighs almost exactly one kilogram.
The US cup
The US legal cup, as used in nutrition labels, equals exactly 240 mL; the US customary cup, used in recipes, equals 236.5882365 mL (half a US liquid pint, or 8 US fluid ounces). Convertitive uses the customary value, which matches how most US cookbooks specify quantities. UK and Australian metric cups are 250 mL — yet another small but consequential difference.
