About Converting Carats per Cubic foot to Stones per Cubic yard
Carat per Cubic foot and Stone per Cubic yard 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
stones per cubic yard = carats per cubic foot × 0.000850354439856
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic foot equals 0.0070629333443 base units, and 1 stone per cubic yard equals 8.30586989761 base units, so dividing one by the other gives the direct carat per cubic foot-to-stone per cubic yard factor of 0.000850354439856.
Simple example
1 ct/ft3 × 0.0008503544399 = 0.0008503544 st/yd3
1 carat per cubic foot = 0.0008503544 stones per cubic yard.
Real-world example
1,000 ct/ft3 × 0.0008503544399 = 0.8503544399 st/yd3
1,000 carats per cubic foot = 0.8503544399 stones per cubic yard.
