To convert cups to milligrams (mg), it’s important to note that cups measure volume and milligrams measure mass. The conversion depends on the density of the substance you’re measuring, since different substances have different densities (e.g., flour, water, sugar, etc.).
For water (which has a density of 1 gram per milliliter), the conversion is relatively straightforward:
1 cup of water = 240 milliliters (mL)
2 Since 1 mL of water weighs 1 gram (g), and 1 gram = 1,000 milligrams (mg):
- cup of water = 240,000 milligrams (mg)
However, for other substances, you’d need to know their density to perform the conversion. For example:
- 1 cup of all-purpose flour weighs around 120 grams, or 120,000 milligrams.
- 1 cup of sugar weighs around 200 grams, or 200,000 milligrams.
General Formula:
Mass in milligrams=Volume in cups×Density of substance in grams per cup×1000.
