Pints to Milliliters
Convert pints (pt) to milliliters (mL). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
milliliters = pints × 473.176473
pints = milliliters × 0.00211337641887
`
One pint is 473.1765 milliliters, and one milliliter is 0.002113 pints.

What Each Unit Is
Pints (pt) — the US liquid pint: half a quart, or 473.176 millilitres. From the Old French pinte; the US kept the pre-1824 English measure.
Milliliters (mL) — one thousandth of a litre, equal to one cubic centimetre. The metric unit for small volumes; medicine and cooking both work in millilitres.
A Sense of Scale
A US pint of beer is 473 mL- A UK pint is 568 mL
- Blood donation takes about a pint
- A teaspoon is 5 mL
- An espresso is 30 mL
- A wine glass pour is 150 mL
Precision
The factor 473.176473 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.
Watch Out For
- A UK pint is 20% larger than a US pint — 568 mL against 473 mL.

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 pt with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 pt becomes | Error |
|---|---|---|---|
| 0 | 473 | 64,801 | 0.0373% |
| 1 | 473.2 | 64,828.4 | 0.0050% |
| 2 | 473.18 | 64,825.66 | 0.0007% |
| 3 | 473.176 | 64,825.11 | — |
| 4 | 473.1765 | 64,825.18 | — |
The right number of significant figures is set by your input, not by the converter. If you measured pints to three significant figures, the answer in milliliters is only good to three — writing more digits claims precision the measurement never had.
