About Converting Carats per Cubic Meter to Grams per Cup
Carat per Cubic Meter and Gram per Cup 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 cup = carats per cubic meter × 0.0000473176473
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 cup equals 4.22675283773 base units, so dividing one by the other gives the direct carat per cubic meter-to-gram per cup factor of 0.0000473176473.
Simple example
1 ct/m3 × 0.0000473176473 = 0.0000473176 g/cup
1 carat per cubic meter = 0.0000473176 grams per cup.
Real-world example
1,000 ct/m3 × 0.0000473176473 = 0.0473176473 g/cup
1,000 carats per cubic meter = 0.0473176473 grams per cup.

Frequently asked questions
How many grams per cup are in 1 carat per cubic meter?
1 carat per cubic meter equals 0.0000473176 grams per cup, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic meter to gram per cup?
Multiply the carat per cubic meter value by 0.0000473176473. The converter above does this instantly to whatever precision you set.
How do I convert gram per cup back to carat per cubic meter?
Use the reverse factor: 1 gram per cup equals 21,133.76419 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 cup?
Gram per Cup (g/cup) is a unit of density.
Is the carat per cubic meter to gram per cup conversion exact?
Yes. Both carat per cubic meter and gram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.0000473176473 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.
