Cooking Measurement Converter
Convert between different cooking measurements and units with ease.
How the Cooking Measurement Converter Works
A cooking measurement converter turns one recipe unit into another so you can follow any recipe, no matter where it was written. Kitchen measurements split into two groups: volume (cups, tablespoons, teaspoons, millilitres) and weight (grams, ounces). Converting within the same group is exact, because the relationship between the units never changes.
Volume conversions are based on fixed ratios. In the United States, 1 cup equals 16 tablespoons, and 1 tablespoon equals 3 teaspoons. Using the US customary system, 1 cup is about 236.6 millilitres, 1 tablespoon is roughly 14.79 millilitres, and 1 teaspoon is about 4.93 millilitres. Many recipes round these to 240 ml per cup and 5 ml per teaspoon for simplicity.
Weight conversions are also exact: 1 ounce equals 28.35 grams, and 1 pound equals 453.6 grams. These never change because grams and ounces both measure mass directly.
- 1 US cup = 16 tbsp = 48 tsp = 236.6 ml
- 1 tablespoon = 3 teaspoons = 14.79 ml
- 1 ounce = 28.35 grams
Why Grams and Cups Depend on the Ingredient
The single most important rule in recipe conversion is this: you cannot convert a cup into grams without knowing the ingredient. Volume measures how much space something takes up, while weight measures how heavy it is. Because every ingredient has a different density, the same cup holds a very different number of grams.
For example, 1 cup of water weighs about 240 grams, but 1 cup of all-purpose flour weighs only around 120-125 grams because flour is light and airy. A cup of granulated sugar weighs roughly 200 grams, and a cup of honey weighs about 340 grams because it is dense. This is why a reliable grams to cups conversion always needs an ingredient-specific density value.
For accuracy in baking, a kitchen scale that measures grams is far more dependable than measuring cups, since flour can be packed loosely or tightly. When a recipe gives weights, weighing your ingredients gives the most consistent results every time.
Common Cooking Conversion Examples
The table below shows handy volume conversions plus typical weights for common ingredients. Remember that weight values shift with the ingredient because of density.
| From | To (volume) | Approx. weight (varies by ingredient) |
|---|---|---|
| 1 cup | 16 tbsp / 236.6 ml | Water 240 g, Flour 120 g, Sugar 200 g |
| 1/2 cup | 8 tbsp / 118 ml | Water 120 g, Flour 60 g, Sugar 100 g |
| 1 tablespoon | 3 tsp / 14.79 ml | Water 15 g, Sugar 12.5 g |
| 1 teaspoon | 4.93 ml | Water 5 g, Salt 6 g |
| 1 ounce (weight) | — | 28.35 g (any ingredient) |
| 100 ml | 6.76 tbsp | Water 100 g, Milk 103 g |
Use the converter above to enter your own amounts. For volume-to-volume and weight-to-weight, results are exact. For volume-to-weight, pick the ingredient so the tool can apply the correct density.
Frequently Asked Questions
It depends entirely on the ingredient. A cup of water is about 240 grams, a cup of flour is roughly 120 grams, and a cup of sugar is around 200 grams. Always choose the ingredient for an accurate grams-to-cups conversion.
There are 16 tablespoons in 1 US cup. A half cup is 8 tablespoons, and a quarter cup is 4 tablespoons. Each tablespoon equals 3 teaspoons.
One US teaspoon is about 4.93 millilitres, usually rounded to 5 ml. A tablespoon is 3 teaspoons, or about 14.79 ml, often rounded to 15 ml.
Only if you know the ingredient's density. For water, 1 ml equals about 1 gram, but oil, honey, and flour all differ. Use the ingredient setting so the tool applies the right factor.
No. A US cup is about 236.6 ml while a UK or metric cup is 250 ml, and an Australian cup is also 250 ml. Check which system your recipe uses to avoid measurement errors.
Weight in grams is more accurate and consistent, especially for baking, because volume measurements vary with how ingredients are packed. A kitchen scale gives the most reliable results.
