This tool converts g to tbsp after you enter the weight of one US cup of the ingredient. No default conversion result is shown because Quirkulator has not verified a reference weight for this ingredient.
Use a kitchen scale to weigh a measured volume from the same batch and preparation you plan to use. Put the empty container on the scale and tare it, then fill your measure without changing the packing method. Convert the measured weight to grams per cup using the table below.
Packing, grinding, moisture and brand can change the weight that fits in a cup. Your result applies to the weight you provide; it is not a universal ingredient density. US customary measures are used: 1 cup = 16 tablespoons = 48 teaspoons = 236.5882365 mL.
The formula
cups = grams ÷ grams per cup
grams per cup- Your measured ingredient weight, converted to the equivalent of one US cup
US cup- 236.5882365 mL; 16 US tablespoons or 48 US teaspoons
How to use this calculator
- Weigh a known volume of the ingredient, using a tared scale and the packing method used in your recipe.
- Convert that measurement to grams per US cup using the table below, then enter it in the required weight field.
- Enter the quantity in g. The calculator first converts it to grams and then to tbsp.
- Keep only as much precision as your scale and volume measurement justify. Measure again if the ingredient or preparation changes.
Worked examples
How to use a smaller measured volume
As a measurement example only, suppose a quarter cup of a sample weighs 10 g. Its cup-equivalent is 10 × 4 = 40 g per cup. A half cup of that same sample would then be estimated at 20 g. These example numbers are not a reference weight for this ingredient.
Frequently asked questions
Why is the cup-weight field blank?
We have not verified a reference weight for this ingredient. You must provide your own measured grams-per-cup value before a result is calculated.
How can I measure less than a full cup?
Weigh a known US volume and scale it to a cup: multiply the weight of a half cup by 2, a quarter cup by 4, a tablespoon by 16, or a teaspoon by 48. A larger measured sample generally reduces the relative effect of scale rounding.
Can I use the weight on a product label?
Only when the label pairs a mass with a clear volume for the same product and preparation. A package weight alone does not tell you its volume. If the label uses a different cup size, convert the volume convention first.
Are fluid ounces and ounces interchangeable?
No. A US fluid ounce measures volume; an avoirdupois ounce measures mass. The calculator keeps them separate and uses your weight measurement when converting between them.
Turn your measurement into grams per US cup
| Volume you weighed | Grams per US cup |
