About Converting Carats per Fluid ounce to Ounce per Cubic inches
Carat per Fluid ounce and Ounce 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
ounce per cubic inches = carats per fluid ounce × 0.00390914902991
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 ounce per cubic inch equals 1729.99404439 base units, so dividing one by the other gives the direct carat per fluid ounce-to-ounce per cubic inch factor of 0.00390914902991.
Simple example
1 ct/fl oz × 0.00390914903 = 0.003909149 oz/in3
1 carat per fluid ounce = 0.003909149 ounce per cubic inches.
Real-world example
1,000 ct/fl oz × 0.00390914903 = 3.90914903 oz/in3
1,000 carats per fluid ounce = 3.90914903 ounce per cubic inches.
