How to Convert Metric Units to US Customary Units

People with a passion for food live across the globe writing amazing recipes and sharing them all over the web. However, because the US uses customary units rather than the metric system, there are a ton of great recipes out there that are confusing to the point of being unusable for a lot of people with no experience converting pounds and cups to grams and liters. Here’s a simple guide to common conversions so that you can use any amazing recipe you find here or Internationally.

Converting Liquid Volume

1 teaspoon = 5mL
1 tablespoon = 1/2 fluid ounces = 15 mL

1/4 cup = 2 fluid ounces = 60 mL
1/3 cup = 80 mL
1/2 cup = 4 fluid ounces = 120 mL
3/4 cup = 6 fluid ounces = 180 mL
1 cup = 8 fluid ounces = 1/2 pint = 240 mL
2 cups = 16 fluid ounces = 1 pint = 475 mL
3 cups = 700 mL
4 cups = 950 mL

If your recipe doesn’t require a ton of precision, converting generally with these statistics is a viable option: 1 cup = 250 mL, 1 pint = 500 mL, 1 quart = 1 L, 1 gallon = 4 L.

Converting Weight

1 ounce = 28 grams
4 ounces = 1/4 pound = 113 grams
1/3 pound = 150 grams
8 ounces = 1/2 pound = 230 grams
2/3 pound = 300 grams
12 ounces = 3/4 pound = 340 grams
16 ounces = 1 pound = 450 grams

Converting Grams to Cups
Converting grams into cups and spoons is somewhat more complicated, since the conversion depends on the type of food. The best way to judge the weight of a cup of any given material is by acquiring a metric scale, but if you can’t do that, here are a few common conversions to help guide you.
