   Start with the number of pints (pt) you want to convert.
2. 2
   Multiply by 0.473176

   The conversion factor from pt to L is 0.473176. Multiply your value by this number.
3. 3
   Read the result in liters

   The result is your value in liters (L).

Multiply the value in pints by 0.473176. For the reverse direction, multiply by 2.113376.

What is the Pint?

The pint equals exactly one half of a US quart (0.473176473 liters) in the United States and 0.568261 liters in the United Kingdom (the imperial pint, 20% larger than the US pint). The British pint is iconic in pub culture — beer and cider are served in imperial pints in UK pubs, and the imperial pint glass is a regulated measure required by law. In the United States, milk is commonly sold by the pint (often as half-quart cartons), and ice cream containers are often pints (16 fl oz US). The pint relates to the gallon (8 pt = 1 gal), the quart (2 pt = 1 qt), the cup (2 cups = 1 US pt), and the fluid ounce (16 fl oz = 1 US pt; 20 fl oz = 1 imperial pt). The discrepancy between US and UK pints reflects the older 1824 imperial reform that the United States did not adopt.

What is the Liter?

The liter equals exactly 1 cubic decimeter (1 dm³ = 0.001 m³) and is the everyday metric unit for liquids worldwide. Adopted as part of the metric system in the 1790s, the liter is used universally for beverages, fuel, household chemicals, and cooking liquids — except in the United States where gallons and fluid ounces dominate. The liter has special connection to mass: pure water at 4°C has almost exactly 1 kg per liter, a relationship designed into the metric system. Soda, milk, and water bottles in metric countries come in 0.5 L, 1 L, 1.5 L, and 2 L sizes. The liter relates to the milliliter (1,000 mL = 1 L), the cubic meter (1,000 L = 1 m³), the US gallon (1 L ≈ 0.264 gal), and the UK gallon (1 L ≈ 0.220 imp gal). Although not strictly an SI base unit, the liter is one of the most-used metric units globally.
