mL to Grams Calculator
Convert milliliters to grams for water, milk, flour, sugar, honey, salt, butter, oil, and more. Free cooking conversion tool with density charts and breakdowns.
About This Calculator
The mL to Grams Calculator converts milliliters (volume) to grams (weight) for common cooking and baking ingredients. Whether you are following a recipe that lists ingredients in grams but only have a measuring jug with milliliters, or you need to convert metric volumes for nutritional tracking, this calculator provides accurate weight equivalents based on each ingredient's unique density.
The conversion uses the standard density formula: weight (g) = volume (mL) × density (g/mL). Water has a density of exactly 1 g/mL at 4°C, making 100 mL of water equal to 100 g. Other ingredients vary significantly — honey is much denser than water, while flour is less dense. This calculator includes density values for 11 common ingredients sourced from food science references and standard cooking data.
How to Use
Enter the volume in milliliters, select the ingredient from the dropdown, and click Calculate. The tool returns the equivalent weight in grams, kilograms, ounces, and pounds, along with a density comparison chart showing relative densities across all supported ingredients.
Regional Notes
India: Recipes often mix metric volumes (mL) with weight (g). This calculator is useful for adapting international recipes to local measuring tools. The density values apply universally regardless of location.
United States: US recipes commonly use cups and ounces. Use this calculator when converting mL measurements from international recipes or food labels to grams for precision cooking.
United Kingdom: UK recipes frequently use grams for dry ingredients and mL for liquids. This calculator helps when a recipe specifies volume but you prefer to weigh ingredients for accuracy.
Frequently Asked Questions
How do you convert milliliters to grams?
To convert mL to grams, multiply the volume in milliliters by the ingredient's density in g/mL. The formula is: weight (g) = volume (mL) × density (g/mL). For water at 4°C, density is 1 g/mL, so 100 mL = 100 g. Different ingredients have different densities — for example, flour is 0.53 g/mL while honey is 1.42 g/mL.
Is 1 mL equal to 1 gram?
1 mL equals 1 gram only for water at 4°C (39.2°F), where density is exactly 1 g/mL. For other ingredients, 1 mL weighs a different amount. For example, 1 mL of flour weighs about 0.53 g, 1 mL of honey weighs about 1.42 g, and 1 mL of milk weighs about 1.03 g.
How many grams is 100 mL of flour?
100 mL of all-purpose flour weighs approximately 53 grams. This is because flour has a density of about 0.53 g/mL. The exact weight can vary slightly depending on how the flour is packed and its moisture content.
How many grams is 200 mL of milk?
200 mL of milk weighs approximately 206 grams. Milk has a density of about 1.03 g/mL, slightly higher than water due to its fat, protein, and mineral content. Whole milk, skim milk, and plant-based milks may have slightly different densities.
Can I convert grams to mL with this calculator?
This calculator converts mL to grams. To convert grams to mL, divide the weight by the ingredient's density. For example, 100 g of flour at 0.53 g/mL equals about 189 mL. You can use the ingredient density chart displayed in the calculator to perform reverse conversions manually.
What is the density of cooking oil in g/mL?
Most cooking oils have a density of approximately 0.92 g/mL at room temperature. This means 100 mL of vegetable oil weighs about 92 grams. Olive oil, canola oil, and sunflower oil all have similar densities in the range of 0.91-0.93 g/mL.
How accurate are the density values used?
The density values are sourced from standard cooking references and food science data. Actual densities can vary by ±5% depending on temperature, brand, and specific variety. For precise baking, weigh your ingredients with a kitchen scale rather than relying on volume-to-weight conversions.
Why do recipes use grams instead of mL for dry ingredients?
Professional bakers and recipes use grams for dry ingredients because weight is more accurate than volume. The same cup of flour can weigh 120-150 g depending on how it is scooped. Using grams eliminates this variability and ensures consistent results every time you bake.
