Gr To Ml Converter
Convert grams (g) or grains (gr) to milliliters (ml) by substance density. Free online mass-to-volume converter with 18+ ingredient presets for cooking, baking, and science.
About This Calculator
The Gr to Ml Converter (grams to milliliters converter) helps you quickly convert between mass and volume for any substance. Whether you are cooking, baking, conducting a science experiment, or working with industrial materials, this tool uses the density of the selected substance to provide accurate conversions. The "gr" abbreviation can refer to both grams (g) and grains (gr) — our converter handles both with the correct conversion factor.
The conversion follows the fundamental physics formula: Volume (ml) = Mass (g) / Density (g/ml). Since different substances have different densities, the same mass can occupy very different volumes. For example, 100 grams of water equals 100 ml, but 100 grams of honey (density 1.42 g/ml) equals only about 70.4 ml. Our density database includes 18 common ingredients including water, milk, flour, sugar, salt, honey, butter, oil, cocoa powder, rice, oats, jam, Nutella, maple syrup, and cream at various fat percentages. You can also enter a custom density for any material not in our presets.
Regional Notes
India (IN): The metric system is standard, with grams and milliliters used universally in cooking, science, and industry. Common ingredient densities match global values. The "gr" abbreviation is rarely used for grains in everyday Indian contexts.
United States (US): While the US commonly uses cups, ounces, and pounds for cooking, grams and milliliters are the standard in scientific and professional culinary settings. The conversion between mass and volume is essential when adapting US recipes to metric measurements or vice versa. Grains (gr) are used in ammunition reloading and jewelry.
United Kingdom (UK): The UK uses both metric (grams, milliliters) and imperial (ounces, pints) measurements. This converter is particularly useful for UK recipes that list ingredients by weight but need volume equivalents, and for scientific and pharmaceutical applications where precise mass-to-volume conversions are critical.
Frequently Asked Questions
How do I convert grams to milliliters?
To convert grams to milliliters, divide the mass in grams by the density of the substance in grams per milliliter (g/ml). The formula is: volume (ml) = mass (g) / density (g/ml). For example, 100 grams of water (density 1.0 g/ml) equals 100 ml, while 100 grams of flour (density 0.53 g/ml) equals approximately 188.68 ml.
What is the difference between grams and grains?
Grams (symbol: g) are a metric unit of mass equal to one-thousandth of a kilogram. Grains (symbol: gr) are an older unit of mass from the apothecary system, primarily used to measure ammunition, arrows, and jewelry. One grain equals exactly 0.06479891 grams. Our calculator supports both units — check the 'Input in grains' option to convert from grains to milliliters.
How many milliliters is 15 grams of sugar?
15 grams of granulated sugar equals approximately 17.65 milliliters. This is calculated by dividing the mass (15 g) by the density of granulated sugar (0.85 g/ml). The exact volume may vary slightly depending on the type of sugar (powdered, brown, or granulated) and its compaction.
Is 1 gram equal to 1 milliliter?
1 gram is equal to 1 milliliter only for pure water at 4°C, where water has a density of exactly 1.0 g/ml. For all other substances, 1 gram does not equal 1 milliliter. For example, 1 gram of honey (density 1.42 g/ml) equals only 0.7 ml, while 1 gram of flour (density 0.53 g/ml) equals about 1.89 ml.
What is the density of common cooking ingredients in g/ml?
Common cooking ingredient densities in g/ml: Water 1.0, Milk 1.03, All-purpose Flour 0.53, Granulated Sugar 0.85, Table Salt 1.217, Honey 1.42, Butter 0.911, Vegetable Oil 0.92, Cocoa Powder 0.53, Rice (raw) 0.85, Oats 0.4, Jam 1.33, Nutella 1.3, Maple Syrup 1.37, Heavy Cream (38% fat) 0.99, Light Cream (13% fat) 1.03.
Is this gr to ml converter free to use?
Yes, this converter is completely free to use with no limitations. You can convert any mass to volume for any substance, access all 18+ preset ingredient densities, and use custom density values. There are no hidden fees, subscriptions, or usage limits.
Can I convert milliliters back to grams with this calculator?
Yes, this calculator supports bidirectional conversion. You can enter either grams (or grains) in the weight field to get milliliters, or enter milliliters in the volume field to get grams. The calculator uses the density of the selected substance for accurate conversion in both directions using the formula: mass = volume × density.
How do I convert grains to grams?
To convert grains to grams, multiply the number of grains by 0.06479891. For example, 100 grains × 0.06479891 = 6.48 grams. Our calculator does this automatically — simply check the 'Input in grains' option and enter your value in grains. The result will show the equivalent volume in milliliters for the selected substance.
