Handy Kitchen Measurement Conversion Guide

While the rest of the world now uses the metric system, just a few countries still stick to the old British Imperial system. These conversion charts will help you understand recipes from around the world!

Even in countries that converted to metric years ago, there are still generations that remember the Imperial system and still use it, at least for some measurements.

This page is a set of tables that will help you convert just about any measurement you need in the kitchen.

Note that these are approximate conversions and may vary slightly depending on the specific ingredient being measured. It’s always a good idea to double-check conversions when using unfamiliar measurements in a recipe.

Liquid Measurements 

Converting measurements within Imperial can be confusing, too. This is exactly why all but three countries thought the metric system was a good idea.

For example, what’s a quart in cups? What’s a gallon in ounces?

Gallons Quarts Cups Fluid Ounces
1 4 16 128
1/2 2 8 64
1/4 1 4 32
1/8 1/2 2 16
1/16 1/4 1 8
1/32 1/8 1/2 4
1/64 1/16 1/4 2

Dry Measurements

And again with the dry measurements. How many teaspoons make 1/3 cup? Now you know!

Cups Tablespoons Teaspoons Fluid Ounces
1 16 48 8
3/4 12 36 6
2/3 10.67 32 5.33
1/2 8 24 4
1/3 5.33 16 2.67
1/4 4 12 2
1/8 2 6 1
1/16 1 3 0.5

Oven Temperatures

And let’s not forget the whole issue of whether your oven is in Celsius or Fahrenheit temperatures. Or what people mean by “warming.”

It’s never going to be the simplest thing to do, making these conversions. But I hope this page makes it easier!
