US pint and Litre
A US pint is 473 ml and an imperial pint is 568 ml — a fifth larger. This is the single most consequential difference between the two systems for anybody following a recipe or ordering a drink.
A litre is a thousand cubic centimetres. It is not strictly an SI unit — the SI unit of volume is the cubic metre — but it is accepted for use with SI and is what fuel, drinks and engines are measured in.

Convert pt to l: common questions
How many litres are in a us pint?
Exactly 0.473176473. One us pint is 0.473176473 litres, and the box above will do it for any figure you type.
Is this conversion exact, or rounded?
The ratio is exact. It is not a rounded constant typed into a table: it is derived from the definitions of the two units, so it agrees with any other correct converter to as many digits as you care to compare.
Why does another converter show a slightly different number?
Almost always rounding rather than disagreement. Many converters cut the answer to two or four decimals, and some carry a factor that was rounded before the multiplication rather than after. The figures here are computed from the exact definitions and only rounded on the way to the screen.
Where these figures come from
The claims this page makes about volume units are checkable, and these are the documents that settle them.
How this page works
