Convert milliliters to grams and grams to ml for any cooking ingredient. Accounts for specific gravity of oils, milk, honey, flour, and 25+ ingredients.
Milliliters and grams are not the same — even though many people treat them interchangeably. One milliliter of water weighs almost exactly 1 gram, but that convenient 1:1 ratio only works for water. A milliliter of honey weighs 1.42 grams. A milliliter of olive oil weighs 0.92 grams. Flour is just 0.53 grams per ml.
This calculator converts between milliliters and grams for 25+ common cooking ingredients using accurate specific gravity data. Whether you're adapting a European recipe (which often uses ml) for an American scale (which reads grams), or converting between volumetric and gravimetric measurements, this tool handles it all.
The key concept is specific gravity (or density relative to water). Water is the baseline at 1.0 g/ml. Ingredients lighter than water (oils, flour) have specific gravity below 1.0. Ingredients heavier than water (honey, syrups, milk) have specific gravity above 1.0. This calculator uses precise specific gravity values for each ingredient.
ML-to-gram conversion varies dramatically by ingredient. Using water's 1:1 ratio for oils, syrups, or flour introduces significant error. This calculator gives accurate, ingredient-specific conversions. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation. Align this note with review checkpoints.
Grams = Milliliters × Specific Gravity. Milliliters = Grams ÷ Specific Gravity. 1 ml = 1 cm³ volume. Specific gravity examples: Water = 1.00, Milk = 1.03, Olive oil = 0.92, Honey = 1.42, Flour = 0.53.
Result: 92 grams
100 ml × 0.92 g/ml = 92 grams. Olive oil is lighter than water because its specific gravity is less than 1.0.
Specific gravity is the ratio of an ingredient's density to water's density. Water = 1.00 by definition. Values above 1 mean heavier than water; below 1 means lighter. Most cooking oils fall between 0.88–0.93. Syrups and honey are 1.3–1.5. Dry ingredients like flour and cocoa are 0.4–0.6 because of the air between particles.
For liquids (water, milk, oil, vinegar), specific gravity is stable and reliable. For dry ingredients (flour, sugar, cocoa), bulk density varies based on how the ingredient is packed, sifted, or scooped. The values in this calculator assume standard spooned (not packed) measurements for dry ingredients.
European and professional recipes often list ingredients in grams. Asian recipes frequently use ml. American recipes use cups and tablespoons. Converting between these systems requires knowing ingredient density. This calculator is the bridge between all three measurement traditions.
Only for water. Other ingredients have different densities. Oil is lighter (1 ml = 0.92g), honey is heavier (1 ml = 1.42g), flour is much lighter (1 ml = 0.53g).
A US cup is 236.6 ml. A metric cup (used in Australia) is 250 ml. A UK cup is approximately 284 ml.
Milliliters measure volume (space occupied), grams measure weight (mass). Liquids are often measured in ml, dry ingredients in grams. This calculator bridges the gap.
Lighter — olive oil floats on water. One ml of oil weighs about 0.92 grams (compared to 1.0 for water).
Use a liquid measuring cup (with pour spout) for large amounts. Use graduated cylinders or syringes for small amounts. Read at eye level at the bottom of the meniscus.
Semi-solids have consistent specific gravity. Yogurt is about 1.03 g/ml. Sour cream is 0.96 g/ml. Measure them as liquids for this conversion.
