About Converting Carats per Cubic Meter to Gram per Cubic inches
Carat per Cubic Meter and Gram per Cubic inch 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
gram per cubic inches = carats per cubic meter × 0.0000032774128
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic meter equals 0.0002 base units, and 1 gram per cubic inch equals 61.0237440947 base units, so dividing one by the other gives the direct carat per cubic meter-to-gram per cubic inch factor of 0.0000032774128.
Simple example
1 ct/m3 × 0.0000032774128 = 0.0000032774 g/in3
1 carat per cubic meter = 0.0000032774 gram per cubic inches.
Real-world example
1,000 ct/m3 × 0.0000032774128 = 0.0032774128 g/in3
1,000 carats per cubic meter = 0.0032774128 gram per cubic inches.

Frequently asked questions
How many gram per cubic inches are in 1 carat per cubic meter?
1 carat per cubic meter equals 0.0000032774 gram per cubic inches, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic meter to gram per cubic inch?
Multiply the carat per cubic meter value by 0.0000032774128. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic inch back to carat per cubic meter?
Use the reverse factor: 1 gram per cubic inch equals 305,118.7205 carats per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic meter?
Carat per Cubic Meter (ct/m3) is a unit of density.
What is a gram per cubic inch?
Gram per Cubic inch (g/in3) is a unit of density.
Is the carat per cubic meter to gram per cubic inch conversion exact?
Yes. Both carat per cubic meter and gram per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 0.0000032774128 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.
