About Converting Carats per Gallon to Megagrams per Quart
Carat per Gallon and Megagram per Quart 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 quart = carats per gallon × 5e-8
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 quart equals 1056688.20943 base units, so dividing one by the other gives the direct carat per gallon-to-megagram per quart factor of 5e-8.
Simple example
1 ct/gal × 5e-8 = 5e-8 Mg/qt
1 carat per gallon = 5e-8 megagrams per quart.
Real-world example
1,000 ct/gal × 5e-8 = 0.00005 Mg/qt
1,000 carats per gallon = 0.00005 megagrams per quart.

Frequently asked questions
How many megagrams per quart are in 1 carat per gallon?
1 carat per gallon equals 5e-8 megagrams per quart, using the exact defined conversion factor rather than an estimate.
How do I convert carat per gallon to megagram per quart?
Multiply the carat per gallon value by 5e-8. The converter above does this instantly to whatever precision you set.
How do I convert megagram per quart back to carat per gallon?
Use the reverse factor: 1 megagram per quart equals 20,000,000 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 quart?
Megagram per Quart (Mg/qt) is a unit of density.
Is the carat per gallon to megagram per quart conversion exact?
Yes. Both carat per gallon and megagram per quart are defined by fixed standards rather than physical artifacts, so the factor of 5e-8 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.
