How Much Is 640 Milliliters of Milk in Grams?
640 milliliters of milk weighs 660.05 g. This is based on milk having a density of 244g per cup. Because milliliters measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 640 milliliters.
Formula and Step-by-Step
- Start with 640 milliliters of milk
- 1 milliliter of milk = 1.03g
- 640 × 1.03 = 660.05g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

Understanding the Units
What is a Milliliter?
A milliliter (ml) is a metric unit of volume equal to 1/1000 of a liter. It is the standard volume measurement for cooking in most countries outside the US. One cup equals approximately 236.588 milliliters.
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
