How to Convert Cooking Measurements
Converting cooking measurements is essential when following recipes from different countries or scaling portions. US recipes use cups, tablespoons, and teaspoons, while most international recipes use milliliters and grams. To convert, select the measurement type you have, enter the amount, and get the equivalent in your desired unit. For baking, precision matters — use the specific converters (cups to mL, tsp to mL) for exact measurements rather than rough estimates.
Cooking Measurement Formulas
1 US Cup = 236.588 mL
1 US Tablespoon = 14.787 mL
1 US Teaspoon = 4.929 mL
1 US Cup = 16 Tablespoons = 48 Teaspoons
1 US Gallon = 16 Cups = 3,785 mL
1 US Fluid Ounce = 29.574 mL
1 Liter = 4.227 US Cups
1 US Gallon = 3.785 Liters
These conversion factors are based on US customary measurements. Note that UK (Imperial) cups and tablespoons differ slightly from US measurements. One Imperial cup equals 284 mL compared to 237 mL for a US cup. Always verify which system your recipe uses before converting.
Example Conversion
Convert 2.5 cups to milliliters:
Formula: mL = cups x 236.588
mL = 2.5 x 236.588
mL = 591.47
So 2.5 US cups = 591.47 mL
Breaking it down:
2 cups = 473.18 mL
0.5 cup (8 tbsp) = 118.29 mL
Total = 591.47 mL

Frequently Asked Questions
How many tablespoons are in a cup?
There are 16 tablespoons in one US cup. This means 1 tablespoon equals 1/16 of a cup, or about 15 mL. For quick mental math: 4 tablespoons = 1/4 cup, 8 tablespoons = 1/2 cup, and 12 tablespoons = 3/4 cup.
What is the difference between US and metric cups?
A US cup equals 236.588 mL, while a metric cup (used in Australia and some other countries) equals exactly 250 mL. The UK Imperial cup equals 284 mL but is rarely used in modern recipes. Most international recipes use milliliters directly rather than cups to avoid confusion.
How do I convert a recipe from metric to US measurements?
Divide milliliters by 236.588 to get cups, or by 14.787 to get tablespoons. For weight measurements (grams), you need to know the ingredient density since volume and weight are not directly interchangeable. For example, 1 cup of flour weighs about 125g, while 1 cup of sugar weighs about 200g.
Is a fluid ounce the same as a weight ounce?
No. A fluid ounce (fl oz) measures volume (29.574 mL), while a weight ounce (oz) measures mass (28.35 grams). They happen to be nearly equal for water, but differ for other ingredients. Honey, for example, weighs more per fluid ounce than water does.
How do I scale a recipe up or down?
To scale a recipe, multiply all ingredient amounts by the same factor. For example, to double a recipe, multiply everything by 2. To make half, multiply by 0.5. For odd scaling (like 1.5x), convert measurements to a single unit first (like mL or grams), multiply, then convert back to practical kitchen measurements.
