Millilitres (water) to Grams (water) (ml to g)
1 ml = 1 g. Multiply millilitres (water) by 1; the box below does it both ways.

How to convert millilitres (water) to grams (water)
- Take the value in millilitres (water).
- Multiply by 1 (because 1 ml = 1 g).
- Example: 15 ml × 1 = 15 g.
- Going back: divide by 1, or multiply by 1.
Where this comes up
Millilitres measure volume and grams measure mass, so there is no fixed conversion: it depends on density. For water (and milk, tea, juice within 3%) 1 ml is 1 g, which is what this page assumes. Oil is lighter (1 ml is 0.92 g), honey heavier (1.42 g), flour much lighter (about 0.55 g per ml when scooped). For anything that is not a watery liquid, weigh it.

Questions people ask
How many grams (water) are in 1 millilitre of water?
1 ml = 1 g. To convert, multiply the millilitre of water value by 1.
What is 100 ml in g?
100 ml is 100 g.
How do I convert grams (water) back to millilitres (water)?
Divide by 1, or multiply by 1: 1 g = 1 ml.
Does this work for oil, milk or flour?
Only approximately. The page assumes the density of water (1 g per ml). Milk is 1.03, cooking oil 0.92, honey 1.42, scooped flour about 0.55, so for anything thick, oily or powdered, weigh it instead.
