The short answer is 16 fluid ounces in a US liquid pint and 20 fluid ounces in a UK imperial pint. The correct number therefore depends on which measurement system you are using.
For an American recipe, drink container, or product label, divide fluid ounces by 16 to get pints. For a British measurement, divide imperial fluid ounces by 20. Use the converter below when you need an answer for another amount.

Why Can One Pint Mean 16 or 20 Ounces?
The United States and the United Kingdom use different pint systems. A US liquid pint contains 16 US fluid ounces. A UK imperial pint contains 20 imperial fluid ounces.
The fluid-ounce units are also defined differently, so it is important to keep each pint with its own fluid-ounce system. Do not divide a US-labelled capacity by 20 or an imperial capacity by 16.
For most bottles, tumblers, and recipes produced for the US market, “pint” means the US liquid pint. In the UK, a pint normally means the imperial pint. Current NIST capacity tables show 16 fluid ounces in a US liquid pint, while its British measurement notes show 20 imperial fluid ounces in a pint.
How to Convert Fluid Ounces to Pints
For US liquid measurements, divide the number of fluid ounces by 16:
US pints = US fluid ounces ÷ 16
For example, 24 US fluid ounces divided by 16 equals 1.5 US pints.
For UK imperial measurements, divide the number of fluid ounces by 20:
Imperial pints = imperial fluid ounces ÷ 20
For example, 30 imperial fluid ounces divided by 20 equals 1.5 imperial pints.
To convert in the opposite direction, multiply instead. Multiply US pints by 16 or imperial pints by 20 to find the matching number of fluid ounces.
Common Ounces-to-Pints Conversions
The table below keeps the two systems separate. The US column uses US fluid ounces, and the UK column uses imperial fluid ounces.
| Fluid ounces | US liquid pints | UK imperial pints |
|---|---|---|
| 4 fl oz | 0.25 pint | 0.2 pint |
| 8 fl oz | 0.5 pint | 0.4 pint |
| 12 fl oz | 0.75 pint | 0.6 pint |
| 16 fl oz | 1 pint | 0.8 pint |
| 20 fl oz | 1.25 pints | 1 pint |
| 24 fl oz | 1.5 pints | 1.2 pints |
| 32 fl oz | 2 pints | 1.6 pints |
| 40 fl oz | 2.5 pints | 2 pints |
Is a 16oz Tumbler the Same as a Pint?
A tumbler labelled 16 US fluid ounces has a nominal capacity of one US pint. A 20oz tumbler equals 1.25 US pints, while a 32oz bottle equals two US pints.
This does not mean that every container described as “pint size” has the same practical fill space. A lid, ice, foam, and the manufacturer’s stated measuring point can affect how much liquid you normally pour into it. Check the labelled capacity rather than judging from the outside shape.
For example, a 12oz, 14oz, or 16oz multi-lid can cooler needs to match the intended can or bottle size. A 20oz vacuum-insulated tumbler represents 1.25 US pints by its stated capacity.
Fluid Ounces and Weight Ounces Are Not the Same
A fluid ounce measures volume. An ounce without “fluid” can refer to weight. They share the word “ounce,” but they do not measure the same property.
When a water bottle, tumbler, measuring cup, or drink menu shows “oz,” it normally refers to fluid ounces because it is describing liquid capacity. When a food package gives the weight of a solid ingredient, ounces usually refer to weight.
You cannot convert weight ounces directly into pints without knowing the substance and its density. The converter on this page is for liquid volume only.
Which Pint System Should You Use?
Use the system attached to the original measurement:
- Choose US liquid for most American recipes, drinkware labels, and container capacities.
- Choose UK imperial for British recipes and drinks measured in imperial pints.
- If the source does not identify the system, check its country and context before calculating.
- Do not use this liquid conversion for a US dry pint, which is a separate measure used for dry goods such as produce.
Keeping the system consistent is more important than memorising a long conversion table. Once you know whether the amount is US or imperial, the calculation is simply division or multiplication by 16 or 20.
Frequently Asked Questions
How many ounces are in a US pint?There are 16 US fluid ounces in one US liquid pint. Divide a US fluid-ounce amount by 16 to convert it to pints.
How many ounces are in a UK pint?There are 20 imperial fluid ounces in one UK imperial pint. Use the imperial setting because an imperial fluid ounce is not the same unit as a US fluid ounce.
Is 16 oz equal to one pint?Yes, 16 US fluid ounces equal one US liquid pint. In the UK imperial system, 16 imperial fluid ounces equal 0.8 pint.
How many pints are in 32 oz?Thirty-two US fluid ounces equal two US liquid pints. Thirty-two imperial fluid ounces equal 1.6 UK imperial pints.
Does this conversion apply to dry pints?No. This page and its converter cover liquid capacity. A US dry pint is a different volume unit and should not be calculated using the US liquid-pint formula.
The Simple Answer to Remember
One US liquid pint contains 16 US fluid ounces, while one UK imperial pint contains 20 imperial fluid ounces. Select the correct system, divide fluid ounces by 16 or 20 to find pints, and multiply by the same number when converting pints back to fluid ounces.
If you are comparing drinkware capacities, use the stated fluid-ounce value rather than relying on descriptions such as “pint size.” For a custom drinkware project, confirm the target market, required fluid-ounce capacity, lid type, and normal fill expectations before approving a product specification.
