About Converting Carats per Cup to Grams per Cubic Meter
Carat per Cup and Gram 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
grams per cubic meter = carats per cup × 845.350567546
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cup equals 0.845350567546 base units, and 1 gram per cubic meter equals 0.001 base units, so dividing one by the other gives the direct carat per cup-to-gram per cubic meter factor of 845.350567546.
Simple example
1 ct/cup × 845.3505675 = 845.3505675 g/m3
1 carat per cup = 845.3505675 grams per cubic meter.
Real-world example
1,000 ct/cup × 845.3505675 = 845,350.5675 g/m3
1,000 carats per cup = 845,350.5675 grams per cubic meter.

Frequently asked questions
How many grams per cubic meter are in 1 carat per cup?
1 carat per cup equals 845.3505675 grams per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cup to gram per cubic meter?
Multiply the carat per cup value by 845.3505675. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic meter back to carat per cup?
Use the reverse factor: 1 gram per cubic meter equals 0.0011829412 carats per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cup?
Carat per Cup (ct/cup) is a unit of density.
What is a gram per cubic meter?
Gram per Cubic Meter (g/m3) is a unit of density.
Is the carat per cup to gram per cubic meter conversion exact?
Yes. Both carat per cup and gram per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 845.3505675 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.
