US pints: beer and drinks, cream and berries. Millilitres: recipes, medicine doses, cosmetics. 1 US pint is about 473 mL.

How we know this is right
The factor is fixed by the standards that define the units, not chosen — so it is exact, not a measurement:
1 mL = 0.002113376419 pt, so 1 pt = 1 ÷ 0.002113376419 = 473.1765 mL.

Every value is carried to full double precision; the display is rounded.
