Grams measure mass while milliliters measure volume, so the ingredient must be known. For water, 100 grams is about 100 milliliters, but flour and honey give different volumes.
Choose an ingredient and enter grams. Results use the same documented density dataset as the kitchen converters on this site.
Enter a non-negative gram amount and choose the ingredient.
Results are practical kitchen estimates based on the selected ingredient state.
Use the calculator for any amount. The chart provides quick reference values.

A milliliter describes the space an ingredient occupies. A gram describes its mass. Dense ingredients fit more grams into the same volume, while lighter ingredients occupy more milliliters for the same weight.
Water is close to one gram per milliliter under ordinary kitchen conditions, which is why the numbers are nearly equal. That shortcut should not be transferred to flour, cocoa, oats, honey or oil.
Powders also change with packing and preparation. The flour result assumes it is fluffed, spooned into the cup and leveled. A tightly scooped cup can contain more grams and produce a different conversion.
These examples show the formula with common amounts.
Using 237 grams per US cup, 100 grams of water is approximately 99.83 mL.
Using 120 grams per US cup, 100 grams of all-purpose flour is approximately 197.16 mL.
Using 340 grams per US cup, 100 grams of honey is approximately 69.59 mL.
