How to Convert Cups to Milligrams
To convert a cup measurement to a milligram measurement, multiply the volume by 236,588.23648 times the density of the ingredient or material.
You can use this simple formula to convert:
Thus, the volume in milligrams is equal to the cups multiplied by 236,588.23648 times the density of the ingredient or material.
Cups and milligrams are both commonly used to measure cooking ingredients.
For cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements.[1] The density of dry ingredients can vary for a variety of reasons, such as compaction.
The best way to ensure an accurate conversion is to use a scale. When a scale is not available, a calculator like the one above is a good way to estimate the volume to weight conversion.

How Many Milligrams are in a Cup?
The actual weight of a cup will vary depending on the density of the material. The table below shows how many milligrams of various wet and dry ingredients are in a cup.

|---|---|---|---|---|---|
| Water | Milk | Cooking Oil | All Purpose Flour | Granulated Sugar | |
| 1/8 c | 29,574 mg | 30,756 mg | 26,025 mg | 15,644 mg | 20,701 mg |
| 1/4 c | 59,147 mg | 61,513 mg | 52,049 mg | 31,289 mg | 41,403 mg |
| 1/3 c | 78,863 mg | 82,017 mg | 69,399 mg | 41,718 mg | 55,204 mg |
| 1/2 c | 118,294 mg | 123,026 mg | 104,099 mg | 62,578 mg | 82,806 mg |
| 2/3 c | 157,725 mg | 164,035 mg | 138,798 mg | 83,437 mg | 110,408 mg |
| 3/4 c | 177,441 mg | 184,539 mg | 156,148 mg | 93,866 mg | 124,209 mg |

Cups
The cup is a unit of volume equal to 16 tablespoons or 8 fluid ounces. The cup should not be confused with the metric cup or the teacup, which are different units of volume. One cup is equal to just under 236.6 milliliters, but in nutrition labeling, one cup is equal to 240 milliliters.[2]
The cup is a US customary unit of volume. Cups can be abbreviated as c, and are also sometimes abbreviated as C. For example, 1 cup can be written as 1 c or 1 C.
Milligrams
The milligram is the mass equal to 1/1,000 of a gram, or 0.0154 grains.
The milligram, or milligramme, is an SI unit of weight in the metric system. In the metric system, "milli" is the prefix for 10-3. Milligrams can be abbreviated as mg; for example, 1 milligram can be written as 1 mg.
