About Converting Carats per Pint to Milligrams per Gallon
Carat per Pint and Milligram per 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
milligrams per gallon = carats per pint × 1600
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per pint equals 0.422675283773 base units, and 1 milligram per gallon equals 0.000264172052358 base units, so dividing one by the other gives the direct carat per pint-to-milligram per gallon factor of 1600.
Simple example
1 ct/pt × 1600 = 1,600 mg/gal
1 carat per pint = 1,600 milligrams per gallon.
Real-world example
1,000 ct/pt × 1600 = 1,600,000 mg/gal
1,000 carats per pint = 1,600,000 milligrams per gallon.

Frequently asked questions
How many milligrams per gallon are in 1 carat per pint?
1 carat per pint equals 1,600 milligrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per pint to milligram per gallon?
Multiply the carat per pint value by 1600. The converter above does this instantly to whatever precision you set.
How do I convert milligram per gallon back to carat per pint?
Use the reverse factor: 1 milligram per gallon equals 0.000625 carats per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per pint?
Carat per Pint (ct/pt) is a unit of density.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
Is the carat per pint to milligram per gallon conversion exact?
Yes. Both carat per pint and milligram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 1600 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.
