About Converting Carats per Milliliter to Stones per Imperial gallon
Carat per Milliliter and Stone per Imperial gallon 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 imperial gallon = carats per milliliter × 0.143177326499
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per milliliter equals 200 base units, and 1 stone per imperial gallon equals 1396.86921728 base units, so dividing one by the other gives the direct carat per milliliter-to-stone per imperial gallon factor of 0.143177326499.
Simple example
1 ct/mL × 0.1431773265 = 0.1431773265 st/imp gal
1 carat per milliliter = 0.1431773265 stones per imperial gallon.
Real-world example
1,000 ct/mL × 0.1431773265 = 143.1773265 st/imp gal
1,000 carats per milliliter = 143.1773265 stones per imperial gallon.

Frequently asked questions
How many stones per imperial gallon are in 1 carat per milliliter?
1 carat per milliliter equals 0.1431773265 stones per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per milliliter to stone per imperial gallon?
Multiply the carat per milliliter value by 0.1431773265. The converter above does this instantly to whatever precision you set.
How do I convert stone per imperial gallon back to carat per milliliter?
Use the reverse factor: 1 stone per imperial gallon equals 6.984346086 carats per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per milliliter?
Carat per Milliliter (ct/mL) is a unit of density.
What is a stone per imperial gallon?
Stone per Imperial gallon (st/imp gal) is a unit of density.
Is the carat per milliliter to stone per imperial gallon conversion exact?
Yes. Both carat per milliliter and stone per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.1431773265 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.
