Milliliters measure volume while grams measure mass. Because different ingredients have different densities, you must know the ingredient's density (g/mL) before converting. Simply multiply the volume in milliliters by the density to get the equivalent mass in grams.
Milliliters to Grams Formula
g = mL × density (g/mL)
For Water, the density is 0.998 g/mL, so the formula becomes:
g = mL × 0.998
Example
Convert 100 mL of Water to g:
100 × 0.998 = 99.8 g

When to Convert Milliliters to Grams
You need to convert milliliters to grams when a recipe lists a liquid or dry ingredient by volume but you want to weigh it on a kitchen scale for greater precision. Weighing in grams is more accurate than measuring by volume, especially for dense or sticky ingredients like honey, peanut butter, or packed flour.
