How to convert ml to grams?
Type a value in either box and pick the ingredient, and the answer shows it in the other unit as you type.
- Grams (g)
- 0.999975
1 mL = 0.999975 g (Water at 4 °C, 0.999975 kg per L).
Grams (g): 0.999975. 1 mL = 0.999975 g (Water at 4 °C, 0.999975 kg per L).
Grams (g) by milliliters (mL)
How to calculate
Converts milliliters to grams and back for water, milk, flour, sugar, and other ingredients, from what each one weighs per liter.
Example with the default inputs (Milliliters (mL) 1, Ingredient Water at 4 °C, 0.999975 kg per L): 1 mL = 0.999975 g (Water at 4 °C, 0.999975 kg per L).
Formula: grams = ml × 0.999975, where kilograms per liter depends on the ingredient (water at 4 °C: 0.999975 kg)
- Grams per cup are USDA FoodData Central (SR Legacy) portion weights for one level US cup (8 US fluid ounces): all-purpose flour 125 g (FDC 168894), granulated sugar 200 g (FDC 169655), brown sugar, packed 220 g (FDC 168833), powdered sugar, unsifted 120 g (FDC 169656), whole milk 244 g (FDC 171265), butter 227 g (FDC 173410), olive oil 216 g (FDC 171413), honey 339 g (FDC 169640), white rice, uncooked 185 g (FDC 169756).
- Water is pure water: 0.999975 kg per liter at 4 °C and 0.998207 kg per liter at 20 °C, from the Tanaka et al. (2001) density formula.
- Other ingredients use their USDA cup weight: kilograms per liter = grams per cup ÷ 236.5882365.
- Exact on the typed decimals: at most 6 decimal places (6 significant digits below 0.0001), rounded half up; an answer of 1 billion or more shows at most 15 significant digits.

Other questions people ask
How many grams are in 1,000 milliliters?
It depends on the ingredient, because a volume does not fix the weight. 1,000 mL is about, in grams: all-purpose flour 528.3; granulated sugar 845.4; brown sugar, packed 929.9; powdered sugar, unsifted 507.2; water at 4 °C 1,000; water at 20 °C 998.2; whole milk 1,031; butter 959.5; olive oil 913; honey 1,433; white rice, uncooked 781.9.
How do I convert ml to grams?
grams = ml × 0.999975, where kilograms per liter depends on the ingredient (water at 4 °C: 0.999975 kg). For example, 1,000 mL of water at 4 °C is 999.975 grams.
Does a liter of water weigh 1 kg?
Almost. Pure water weighs 0.999975 kg per liter at 4 °C, where it is densest, and 0.998207 kg per liter at 20 °C (Tanaka et al. 2001). Other liquids differ more: a liter of whole milk weighs about 1.03 kg and a liter of olive oil about 0.91 kg (USDA).
How many grams is 1 mL of milk?
1.031328 g: USDA lists a cup of whole milk at 244 g, and a US cup is 236.5882365 mL.
