About Converting Carats per Fluid ounce to Grains per Fluid ounce
Carat per Fluid ounce and Grain per Fluid ounce 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 fluid ounce = carats per fluid ounce × 3.08647167059
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 fluid ounce equals 2.19111181379 base units, so dividing one by the other gives the direct carat per fluid ounce-to-grain per fluid ounce factor of 3.08647167059.
Simple example
1 ct/fl oz × 3.086471671 = 3.086471671 gr/fl oz
1 carat per fluid ounce = 3.086471671 grains per fluid ounce.
Real-world example
1,000 ct/fl oz × 3.086471671 = 3,086.471671 gr/fl oz
1,000 carats per fluid ounce = 3,086.471671 grains per fluid ounce.
