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 teaspoon equals 1/3 of a US tablespoon, or about 4.929 mL. The metric teaspoon (used on most non-US nutrition labels) is exactly 5 mL — close enough that you can substitute freely in cooking but not in precise dosing.
