About Converting Grains per Fluid ounce to Carat per Cubic inches
Grain per Fluid ounce and Carat per Cubic inch 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
carat per cubic inches = grains per fluid ounce × 0.179529447619
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per fluid ounce equals 2.19111181379 base units, and 1 carat per cubic inch equals 12.2047488189 base units, so dividing one by the other gives the direct grain per fluid ounce-to-carat per cubic inch factor of 0.179529447619.
Simple example
1 gr/fl oz × 0.1795294476 = 0.1795294476 ct/in3
1 grain per fluid ounce = 0.1795294476 carat per cubic inches.
Real-world example
1,000 gr/fl oz × 0.1795294476 = 179.5294476 ct/in3
1,000 grains per fluid ounce = 179.5294476 carat per cubic inches.
