568.261 UK pints

How the pints to ml conversion works

The conversion depends on which pint you mean: 1 UK (imperial) pint = 568.261 ml, while 1 US liquid pint = 473.176 ml. So millilitres = pints × 568.261 (UK) or × 473.176 (US). Going the other way, divide by the same figure. Pick the pint type above — a UK pint is about 20% bigger than a US pint.

Worked example: a British recipe calling for 2 pints of milk needs 2 × 568.261 = 1,136.522 ml. The same 2 US pints is 2 × 473.176 = 946.352 ml — a difference of nearly 200 ml.

The trap: a UK pint is 20 UK fluid ounces and a US pint is 16 US fluid ounces, and the fluid ounces differ too — so the two pints are not just a different count of the same ounce. For litres, see our liters to pints converter, and for cups see pints to cups.
