About Converting Grams per Cubic Meter to Carats per Cubic Meter
Gram per Cubic Meter and Carat per Cubic Meter 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. Both are mass per volume density units.
Formula
carats per cubic meter = grams per cubic meter × 5
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic meter equals 0.001 base units, and 1 carat per cubic meter equals 0.0002 base units, so dividing one by the other gives the direct gram per cubic meter-to-carat per cubic meter factor of 5.
Simple example
1 g/m3 × 5 = 5 ct/m3
1 gram per cubic meter = 5 carats per cubic meter.
Real-world example
1,000 g/m3 × 5 = 5,000 ct/m3
1,000 grams per cubic meter = 5,000 carats per cubic meter.

Frequently asked questions
How many carats per cubic meter are in 1 gram per cubic meter?
1 gram per cubic meter equals 5 carats per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic meter to carat per cubic meter?
Multiply the gram per cubic meter value by 5. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic meter back to gram per cubic meter?
Use the reverse factor: 1 carat per cubic meter equals 0.2 grams per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per cubic meter?
Gram per Cubic Meter (g/m3) is a unit of density.
What is a carat per cubic meter?
Carat per Cubic Meter (ct/m3) is a unit of density.
Is the gram per cubic meter to carat per cubic meter conversion exact?
Yes. Both gram per cubic meter and carat per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 5 used above is exact to as many digits as you choose to display.
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.
