For water, 1 g is almost exactly 1 mL. For other ingredients it is not: 100 g of flour fills about 190 mL, while 100 g of honey takes only about 70 mL.
How to use the Grams to mL Converter
- Ingredient
- Custom density
- Grams
- Every result field is editable: type into Millilitres or any other result and Grams plus every other field update to match.
Results update as you type, and every field accepts the units shown in its menu.
How it works
The calculator converts your weight to SI units, looks up the density of the selected ingredient in kg/m³ and divides. The result is then shown in millilitres and other common units. Every result field is editable, so you can work backwards too.
How to convert grams to millilitres
- Find the density of the ingredient (the menu fills it in for you).
- Convert the weight to SI units if needed.
- Divide mass by density to get volume.
- Convert the answer to millilitres.

What each result means
- Millilitres = [Grams] ÷ [Density used]
- US cups = [Grams] ÷ [Density used]
- Tablespoons (US) = [Grams] ÷ [Density used]
Formula
volume = mass ÷ densityWorked example
Inputs — Ingredient: Water; Custom density: 1 g/cm³; Grams: 100 g.
Results — Density used = 1 g/cm³; Millilitres = 100 mL; US cups = 0.422675 US cup; Tablespoons (US) = 6.762805 tbsp.
Frequently asked questions
Is 1 gram the same as 1 mL?
Only for water and similar liquids.
How many mL is 100 g of flour?
About 189 mL.
Why does the answer change with the ingredient?
Grams and millilitres measure different things (weight and volume), so the conversion depends on how dense the material is.
What if my ingredient is not listed?
Choose “Custom density” and type its density; the label or a quick weigh-and-measure test will give it.
What formula does the Grams to mL Converter use?
volume = mass ÷ density.
