About Converting Grains per Gallon to Micrograms per Cubic Centimeter
Grain per Gallon and Microgram per Cubic Centimeter 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
micrograms per cubic centimeter = grains per gallon × 17.1180610453
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per gallon equals 0.0171180610453 base units, and 1 microgram per cubic centimeter equals 0.001 base units, so dividing one by the other gives the direct grain per gallon-to-microgram per cubic centimeter factor of 17.1180610453.
Simple example
1 gr/gal × 17.11806105 = 17.11806105 ug/cm3
1 grain per gallon = 17.11806105 micrograms per cubic centimeter.
Real-world example
1,000 gr/gal × 17.11806105 = 17,118.06105 ug/cm3
1,000 grains per gallon = 17,118.06105 micrograms per cubic centimeter.

Frequently asked questions
How many micrograms per cubic centimeter are in 1 grain per gallon?
1 grain per gallon equals 17.11806105 micrograms per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per gallon to microgram per cubic centimeter?
Multiply the grain per gallon value by 17.11806105. The converter above does this instantly to whatever precision you set.
How do I convert microgram per cubic centimeter back to grain per gallon?
Use the reverse factor: 1 microgram per cubic centimeter equals 0.0584178312 grains per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a microgram per cubic centimeter?
Microgram per Cubic Centimeter (ug/cm3) is a unit of density.
Is the grain per gallon to microgram per cubic centimeter conversion exact?
Yes. Both grain per gallon and microgram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 17.11806105 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.
