Why you’ll love this conversion chart
Cooking and baking can be confusing enough, without the headaches of having to convert from one measurement system to another. It’s always frustrating when you find a recipe you really want to make, only to realise the ingredients aren’t listed in a measurement you’re familiar with.
This has happened to me more times than I can count, and I assume I’m not alone in my frustrations! So I created this helpful article in the hope of preventing future headaches for you, me, and everyone else!
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.
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.
