About Converting Carats per Gallon to Stones per Cubic Meter
Carat per Gallon and Stone 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
stones per cubic meter = carats per gallon × 0.00831999546699
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per gallon equals 0.0528344104716 base units, and 1 stone per cubic meter equals 6.35029318 base units, so dividing one by the other gives the direct carat per gallon-to-stone per cubic meter factor of 0.00831999546699.
Simple example
1 ct/gal × 0.008319995467 = 0.0083199955 st/m3
1 carat per gallon = 0.0083199955 stones per cubic meter.
Real-world example
1,000 ct/gal × 0.008319995467 = 8.319995467 st/m3
1,000 carats per gallon = 8.319995467 stones per cubic meter.

Frequently asked questions
How many stones per cubic meter are in 1 carat per gallon?
1 carat per gallon equals 0.0083199955 stones per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per gallon to stone per cubic meter?
Multiply the carat per gallon value by 0.008319995467. The converter above does this instantly to whatever precision you set.
How do I convert stone per cubic meter back to carat per gallon?
Use the reverse factor: 1 stone per cubic meter equals 120.1923732 carats per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
What is a stone per cubic meter?
Stone per Cubic Meter (st/m3) is a unit of density.
Is the carat per gallon to stone per cubic meter conversion exact?
Yes. Both carat per gallon and stone per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 0.008319995467 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.
