About Converting Carats per Fluid ounce to Grains per Gallon
Carat per Fluid ounce and Grain 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
grains per gallon = carats per fluid ounce × 395.068373835
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per fluid ounce equals 6.76280454037 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct carat per fluid ounce-to-grain per gallon factor of 395.068373835.
Simple example
1 ct/fl oz × 395.0683738 = 395.0683738 gr/gal
1 carat per fluid ounce = 395.0683738 grains per gallon.
Real-world example
1,000 ct/fl oz × 395.0683738 = 395,068.3738 gr/gal
1,000 carats per fluid ounce = 395,068.3738 grains per gallon.
