Only water (and very water-like liquids) have a 1:1 ratio between millilitres and grams. Oils are lighter than water, syrups and honey are heavier, and powders like flour are much lighter because of the air between particles.
How to use the ml to Grams Calculator
- Ingredient
- Grams per US cup (custom ingredient)
- Volume
- Every result field is editable: type into Weight and Volume 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
Choose the ingredient and enter the volume in millilitres (or type grams into the result).
Inputs explained
| Field | What to enter |
|---|---|
| Ingredient | Choose one: Water, Milk, Buttermilk, Heavy cream (36–40% fat) … |
| Grams per US cup (custom ingredient) | A number |
| Volume | Units: ml, cups, fl oz, L, tbsp |
Example values
How the main result changes when Volume changes and everything else stays at the example values above:
| Volume (ml) | Weight (g) |
|---|---|
| 125 | 125 |
| 187.5 | 187.5 |
| 250 | 250 |
| 312.5 | 312.5 |
| 375 | 375 |
| 500 | 500 |
Formula
Grams = millilitres × density (g/ml)
Water: 1 ml = 1 g; milk ≈ 1.03 g/ml; honey ≈ 1.42 g/ml; oil ≈ 0.84 g/ml
Worked example
Inputs — Ingredient: Water; Volume: 250 ml.
Results — Weight = 250 g; Density = 1 g/ml.
