What is the UK unit of liquid?

The most commonly used UK liquid measures are metric litres and millilitres. Although, just to confuse you, we still use pints to measure a handful of items – such as milk and beer.

How to convert liquid volume units?

There are a wide variety of liquid volume units used around the world, and different equations to convert between each one. You need to have a basic understanding of them before you can convert them. Usually, where your recipe author is based will determine the volume units called for.

If you’re using a UK recipe, the liquid measurements will be in teaspoons, tablespoons, millilitres, litres, or British imperial pints.

If you’re using a US recipe, the liquid measurements will be in teaspoons, tablespoons, fluid ounces, cups, US pints, quarts or gallons.

Once you have a firm grasp on this you can use a liquid conversion calculator or chart to convert between them.

UK volume measures explained

In the UK, we tend to use metric for most of our volume measuring needs. The units are most commonly: millilitres (ml) > litres (l).

There are 1000 millilitres in 1 litre. For example, 1.5 litres would be equal to 1500 millilitres.

For occasional items we still use pints (pt). 1 British imperial pint is equal to 568ml. Which is just over half a litre.

US volume measures explained

The US use imperial volume measures as standard. The units are fluid ounces (fl oz) > cups (c) > US pints (pt) > quarts (qt) > gallons (gal).

There are 8 fluid ounces in 1 cup, 16 in 1 US pint, 33 in 1 quart, and 133 in 1 gallon.

There’s 2 cups in 1 US pint, 4 in 1 quart, and 16 in 1 gallon.

There are 2 US pints in 1 quart, and 8 in 1 gallon.

There’s 4 quarts in 1 gallon.

Are UK and US teaspoons and tablespoons the same?

No, they’re not quite the same. Just to confuse you even more, a UK teaspoon is 4.92ml and a US teaspoon is 5ml. A UK tablespoon is 14.2ml, while a US tablespoon is 14.8ml.

Although baking is somewhat of a science, the minute differences between UK and US spoon measures rarely have any major effects on your finished baked goods.

Is a pint the same in the UK and US?

No. A pint in the UK/Europe typically measures 568ml. Whereas a pint in the US is 473ml. The difference is down to the two varying measurement systems that define each one.

How many fluid ounces are in a litre of liquid?

Fluid ounces is a liquid volume measurement that’s commonly used in the US, and a litre is part of the metric system that’s used in the UK. There are 35 fluid ounces in 1 litre of liquid.

How many ml are in an oz?

The US use fluid ounces (fl oz) as part of their imperial liquid measurement scale. The UK and Europe typically use metric litres and millilitres. 1 US fluid ounce (fl oz) is equal to 28.5ml.

Helpful liquid conversion tips!

Here are some tips you’ll find helpful when you are using measurement conversion charts.

Read through this whole post before using a liquids conversion chart. If you have a general understanding of the differences between UK and US systems, you’re less likely to make costly mistakes.
Don’t switch between metric and imperial mid bake, stick with one the whole way through. Due to the numbers often being rounded up or down when converting between units, it could upset the delicate ratios of your recipe.
Make sure you read the notes carefully. What may seem the same at first, might actually not be. For example, a US pint is smaller than a UK pint.
