About Converting Grams per Cubic Centimeter to Metric tons per Cubic Millimeter

Gram per Cubic Centimeter and Metric ton 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

metric tons per cubic millimeter = grams per cubic centimeter × 1e-9

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 metric ton per cubic millimeter equals 1000000000000 base units, so dividing one by the other gives the direct gram per cubic centimeter-to-metric ton per cubic millimeter factor of 1e-9.

Simple example

1 g/cm3 × 1e-9 = 1e-9 t/mm3

1 gram per cubic centimeter = 1e-9 metric tons per cubic millimeter.

Real-world example

1,000 g/cm3 × 1e-9 = 0.000001 t/mm3

1,000 grams per cubic centimeter = 0.000001 metric tons per cubic millimeter.

Frequently asked questions

How many metric tons per cubic millimeter are in 1 gram per cubic centimeter?

1 gram per cubic centimeter equals 1e-9 metric tons per cubic millimeter, using the exact defined conversion factor rather than an estimate.

How do I convert gram per cubic centimeter to metric ton per cubic millimeter?

Multiply the gram per cubic centimeter value by 1e-9. The converter above does this instantly to whatever precision you set.

How do I convert metric ton per cubic millimeter back to gram per cubic centimeter?

Use the reverse factor: 1 metric ton per cubic millimeter equals 1,000,000,000 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 metric ton per cubic millimeter?

Metric ton per Cubic Millimeter (t/mm3) is a unit of density.

Is the gram per cubic centimeter to metric ton per cubic millimeter conversion exact?

Yes. Both gram per cubic centimeter and metric ton per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 used above is exact to as many digits as you choose to display.

Where is the gram per cubic centimeter still used today?

Standard density unit in chemistry and materials science worldwide

What's the difference between density and mass concentration?

Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
