Pints to mL Converter

by

Enter pints, choose US liquid, US dry, or Imperial, and get the matching volume in milliliters.

Advanced options
Equivalent volume in milliliters
mL
Use this as the converted mL amount. If the source did not identify its pint standard, verify that choice before relying on the answer.
Pint standard used
A different pint type produces a different mL answer for the same quantity.
Milliliters in one selected pint
mL/pt
Multiply any quantity in the selected pint type by this factor to get mL.

How to use our Pints to mL Converter

  1. Enter the quantity from your recipe, package, worksheet, or note in "Pints (pt)". Decimals, fractions such as 1/4, and mixed numbers such as 1 1/2 work.
  2. Choose the matching "Pint type". Use "US dry pint" only when the source says dry pint, and choose "Imperial pint" only when the source identifies that standard.
  3. Click "Calculate" to see the equivalent volume in mL.
  4. Read the "Pint standard used" card before copying the number. The same number of pints gives different mL amounts under different standards.
  5. Open "Advanced options" if an assignment or measuring tool requires a different number of displayed decimal places.

Definitions

Pint (pt): A volume unit. Its size depends on whether it is a US liquid, US dry, or Imperial pint.

US liquid pint: A US volume unit commonly used for liquids. One US liquid pint is 473.176473 mL.

US dry pint: A different US volume unit used only when a source identifies a dry pint. One US dry pint is 550.6104713575 mL.

Imperial pint: A volume unit in the Imperial system. One Imperial pint is 568.26125 mL.

Milliliter (mL): A metric volume unit equal to one thousandth of a liter.

Conversion factor: The number of milliliters in one pint of the selected type.

Common mistakes and quick fixes

Mistake: Treating every pint as the same volume.
Fix: Select the pint type named by the source before calculating.

Mistake: Selecting a US dry pint for a normal US liquid recipe.
Fix: Choose "US liquid pint" unless the source specifically says "dry pint."

Mistake: Using an Imperial pint for a US source, or a US pint for an Imperial source.
Fix: Check the source wording and country. Select "Imperial pint" only when that standard is stated.

Mistake: Typing 1,01 to mean one point zero one pints.
Fix: Use 1.01. Commas are only for thousands separators, such as 1,000.

Mistake: Rounding before converting.
Fix: Enter the original amount and use the displayed mL result. Change decimal places only after checking the pint type.

Limitations & Key Assumptions / Boundary Conditions

  • The answer depends on the selected pint standard. If a source says only "pint," check which system it uses before relying on the conversion.
  • This is a volume converter, not a weight converter. A pint of an ingredient does not have a fixed weight because density and packing can vary.
  • Changing displayed decimal places changes rounding only. The calculation uses the full conversion factor.
  • Recipe measures, package markings, and measuring cups may already be rounded, even when the converted answer shows more digits.
  • Only zero and positive pint quantities are accepted. Negative volume amounts are outside this converter's range.

Methodology

Calculation

The converter selects a milliliters-per-pint factor for the chosen pint type, then multiplies that factor by the entered quantity. The three pint types use different factors because they are different volume units. [1]

milliliters = pints x milliliters per selected pint

US liquid: 473.176473 mL/pt; US dry: 550.6104713575 mL/pt; Imperial: 568.26125 mL/pt

Worked example

For 1.5 US liquid pints, multiply 1.5 by 473.176473 mL per pint.

1.5 x 473.176473 = 709.7647095 mL

At three decimal places, the displayed answer is 709.765 mL. Rounding happens after multiplication, not before it.
