Pints to Liters
Convert pints (pt) to liters (L). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
liters = pints × 0.473176473
pints = liters × 2.11337641887
`
One pint is 0.473176 liters, and one liter is 2.1134 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.
Liters (L) — exactly one cubic decimetre, or 0.001 cubic metres. A metric volume defined for trade; briefly redefined against the kilogram before reverting in 1964.
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 large drink bottle is 2 L
- A car fuel tank is 45–60 L
- A bath holds about 80 L
Doing It in Your Head
Multiply by 8, then divide by 17. That is off by 0.55% — close enough to judge a
distance, a weight or a price, and not close enough to sign off on a drawing.

Precision
The factor 0.473176473 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.
In Code

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 | 0 | 0 | 100.0000% |
| 1 | 0.5 | 68.5 | 5.6688% |
| 2 | 0.47 | 64.39 | 0.6713% |
| 3 | 0.473 | 64.801 | 0.0373% |
| 4 | 0.4732 | 64.8284 | 0.0050% |
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 liters is only good to three — writing more digits claims precision the measurement never had.
