Fluid Ounces to Pints (fl oz to pt)

Common questions

How many fluid ounces are in a pint?

One imperial pint is exactly 20 imperial fluid ounces, so 20 imperial fl oz is 1 imperial pt, 10 is 0.5 pt and 5 is 0.25 pt. One US liquid pint is instead 16 US fluid ounces, so 8 US fl oz is 0.5 US pt. The definitions are 568.26125 mL per imperial pint and 473.176473 mL per US liquid pint. A container’s word pint alone does not establish which convention its label uses; choose matching labeled units.

What is 1 fl oz in pints?

0.05 imperial pints, a twentieth of one. The amounts asked for next most often, all in imperial: 2 fl oz is 0.1 pt, 4 fl oz is 0.2 pt, 8 fl oz is 0.4 pt, 12 fl oz is 0.6 pt, 16 fl oz is 0.8 pt, 25 fl oz is 1.25 pt and 40 fl oz is 2 pt. Type any of them into the From box and the headline changes without pressing anything. In US measure 1 fl oz is 0.0625 pints, because the division is by 16 rather than 20. The Copy result button under the stage copies the headline exactly as printed, without the thousands separators, so it pastes straight into a spreadsheet.

Is this the UK pint or the US pint, and can I switch?

It opens on the imperial pair, Fluid ounce (imperial) into Pint (imperial). Both menus carry the US sizes at all times, so choosing Fluid ounce (US) and Pint (US) divides by 16 instead of 20 and nothing else about the page changes. Mixing the two systems gives a real answer as well, and this is where a bar or a recipe usually goes astray: 1 imperial fluid ounce is 0.0600474962752 US pints, and 1 US fluid ounce is 0.0520421365393 imperial pints. The Swap units button between the two boxes turns this page into a pints to fluid ounces converter without reloading it.

How many millilitres is a pint, and how many is a fluid ounce?

An imperial pint is 568.26125 mL and an imperial fluid ounce is 28.4130625 mL, both exact, because the imperial gallon is defined as exactly 4.54609 litres, a pint is an eighth of that gallon and a fluid ounce is a twentieth of the pint. A US pint is 473.176473 mL and a US fluid ounce is 29.5735295625 mL, which come from the US gallon of exactly 231 cubic inches. Millilitres and litres are the first two rows of the list under the answer, so the metric figure is on screen beside the pints for whatever amount you type.

Why is the pint missing from the list under the answer?

Because this converter counts the imperial units as uncommon and keeps them out of that list by default, so the list stays short for the units most people want. The headline at the top is the imperial pint answer regardless, and ticking the switch marked Show 5 more adds the imperial pint, imperial gallon, cubic inch and cubic foot rows underneath it. The Pint (US) row is there from the start, so 16 fl oz reads 0.8 in the headline and 0.960759940404 in that row at the same time.

What is 16 fl oz in pints, and what about 20 fl oz?

16 imperial fluid ounces is 0.8 of an imperial pint, and 20 imperial fluid ounces is exactly 1. The 16 that people usually have in mind comes from a US cup or can, and 16 US fluid ounces is exactly 1 US pint, so pick the US units in both menus for that reading. In millilitres the two sixteens are far apart: 16 imperial fl oz is 454.609 mL and 16 US fl oz is 473.176473 mL.

Can I type half a pint as a fraction?

Fractions such as 1/2 are refused. Enter a decimal and select its unit: to convert half an imperial pint, choose Pint (imperial) in From and type 0.5. With this page’s initial imperial-fluid-ounce From unit, 0.5 instead means half a fluid ounce and displays as 0.025 imperial pt; 2.5 fl oz is 0.125 pt and 7.5 fl oz is 0.375 pt. Decimal and scientific numbers with a matching suffix are accepted; 1,000 is a properly grouped thousand, while a decimal comma is refused. The Fraction Calculator can turn a fraction into a decimal first, which can still be rounded.

Is a fluid ounce the same as an ounce on the scales?

An imperial fluid ounce is a volume of exactly 28.4130625 mL; an avoirdupois ounce is a mass of exactly 28.349523125 g. They are different dimensions even though their numeric coefficients look similar. Volume and Mass remain separate categories. Converting a food or liquid volume to mass requires a stated density or ingredient convention; the linked Grams to Cups tool supplies its own labeled ingredient assumptions. This page does not infer density from a fluid-ounce count.

Does anything I type leave my browser?

Your input and converted values are calculated in the browser and are not uploaded by the converter. The definitions arrive with the page, so conversion needs no external data lookup and keeps working offline after the page has loaded. The core conversion needs no account. This focused page preserves the main converter’s saved unit pair. A saved value and uncommon-unit preference can travel between pages when storage is usable, but a suffix must still match From. Only valid deliberate scalar edits save those fields after a short delay; invalid or incomplete drafts preserve the prior record. Unusable or conflicting records remain until you use Forget saved settings, which keeps the current conversion on screen.
