About Converting Grams per Cubic Centimeter to Grains per Cubic Millimeter
Gram per Cubic Centimeter and Grain per Cubic Millimeter both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Gram per Cubic Centimeter is most often used for material identification in chemistry and geology (mineral density tables).
Formula
grains per cubic millimeter = grams per cubic centimeter × 0.0154323583529
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic centimeter equals 1000 base units, and 1 grain per cubic millimeter equals 64798.91 base units, so dividing one by the other gives the direct gram per cubic centimeter-to-grain per cubic millimeter factor of 0.0154323583529.
Simple example
1 g/cm3 × 0.01543235835 = 0.0154323584 gr/mm3
1 gram per cubic centimeter = 0.0154323584 grains per cubic millimeter.
Real-world example
1,000 g/cm3 × 0.01543235835 = 15.43235835 gr/mm3
1,000 grams per cubic centimeter = 15.43235835 grains per cubic millimeter.

Frequently asked questions
How many grains per cubic millimeter are in 1 gram per cubic centimeter?
1 gram per cubic centimeter equals 0.0154323584 grains per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic centimeter to grain per cubic millimeter?
Multiply the gram per cubic centimeter value by 0.01543235835. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic millimeter back to gram per cubic centimeter?
Use the reverse factor: 1 grain per cubic millimeter equals 64.79891 grams per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per cubic centimeter?
Gram per Cubic Centimeter (g/cm3) measures density. Numerically identical to kilograms per liter, since one cubic centimeter equals one milliliter — this is the form most commonly used in chemistry and materials-science textbooks. It is classified as a metric derived density unit.
What is a grain per cubic millimeter?
Grain per Cubic Millimeter (gr/mm3) is a unit of density.
Is the gram per cubic centimeter to grain per cubic millimeter conversion exact?
Yes. Both gram per cubic centimeter and grain per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.01543235835 used above is exact to as many digits as you choose to display.
Where is the gram per cubic centimeter still used today?
