About Converting Carats per Gallon to Megagrams per Gallon
Carat per Gallon and Megagram 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
megagrams per gallon = carats per gallon × 2e-7
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 megagram per gallon equals 264172.052358 base units, so dividing one by the other gives the direct carat per gallon-to-megagram per gallon factor of 2e-7.
Simple example
1 ct/gal × 2e-7 = 2e-7 Mg/gal
1 carat per gallon = 2e-7 megagrams per gallon.
Real-world example
1,000 ct/gal × 2e-7 = 0.0002 Mg/gal
1,000 carats per gallon = 0.0002 megagrams per gallon.

Frequently asked questions
How many megagrams per gallon are in 1 carat per gallon?
1 carat per gallon equals 2e-7 megagrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per gallon to megagram per gallon?
Multiply the carat per gallon value by 2e-7. The converter above does this instantly to whatever precision you set.
How do I convert megagram per gallon back to carat per gallon?
Use the reverse factor: 1 megagram per gallon equals 5,000,000 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 megagram per gallon?
Megagram per Gallon (Mg/gal) is a unit of density.
Is the carat per gallon to megagram per gallon conversion exact?
Yes. Both carat per gallon and megagram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 2e-7 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.
