Pints to Liters Converter

Volumetric Metrology & The Transatlantic Pint Discrepancy

The pint (pt) varies significantly between US and British customary systems:

• **

• US Liquid Pint (NIST Handbook 44)**:

1 US liquid pt (1) / (8) US Gallon = 16 US fl oz = 0.473176473 L = 473.176 mL

Liters (L) = US Pints × 0.473176473, US Pints = Liters × 2.113376

• **

• UK Imperial Pint (Weights and Measures Act)**:

1 UK Imp pt (1) / (8) Imp Gallon = 20 Imp fl oz = 0.56826125 L = 568.261 mL

Liters (L) = Imp Pints × 0.56826125, Imp Pints = Liters × 1.759754

• **

• Standard Volume Benchmarks**:

• 1.0 US Liquid Pint = 0.4732 L = 473.18 mL = 16.00 fl oz

• 1.0 UK Imperial Pint = 0.5683 L = 568.26 mL = 20.00 fl oz

• 1.0 US Dry Pint = 0.5506 L = 550.61 mL

• 2.0 US Pints (1 Quart) = 0.9464 L = 946.35 mL

• 8.0 US Pints (1 Gallon) = 3.7854 L = 3,785.41 mL

• 1.0 Liter = 2.1134 US Pints = 1.7598 UK Pints

How to Use This Calculator

Enter your Volume Value to Convert (e.g. 1), Pint Measurement System — choose from US Liquid Pint (16 US fl oz = 0.4732 L = 473.18 mL - US Standard), UK Imperial Pint (20 Imp fl oz = 0.5683 L = 568.26 mL - British Pub Glass), US Dry Pint (33.60 cu in = 0.5506 L = 550.61 mL - Berry Basket), Conversion Direction — choose from Pints (pt) to Liters (L = pt × liters_per_pt), Liters (L) to Pints (pt = L ÷ liters_per_pt), and Pub & Dairy Benchmark — choose from Custom Volume Value, 1.0 US Liquid Pint → 0.4732 Liters (16.0 fl oz / 473.18 mL), 1.0 UK Imperial Pint (Pub Glass) → 0.5683 Liters (20.0 Imp fl oz / 568.26 mL). Results update instantly as you type — adjust any value to compare scenarios.

Mathematical relationships extracted from calculation logic:

litersPerPint = 0.473176473; // US Liquid Pint: 3.785411784 / 8

liters = pints * litersPerPint

mL = liters * 1000.0

flOz = pints * flOzFactor

cups = pints * 2.0

quarts = pints / 2.0

Reference constants:

litersPerPint = 0.473176473

flOzFactor = 16.0

Worked Example

A homebrewer brewing an English ale recipe calling for 8 imperial pints of water converts the volume into metric liters as 8 × 0.568261 = 4.5461 liters (exact 1.0 Imperial Gallon).

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
