About Converting Stones per Cubic yard to Long tons per Cubic Centimeter
Stone per Cubic yard and Long ton per Cubic Centimeter 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
long tons per cubic centimeter = stones per cubic yard × 8.174691e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cubic yard equals 8.30586989761 base units, and 1 long ton per cubic centimeter equals 1016046908.8 base units, so dividing one by the other gives the direct stone per cubic yard-to-long ton per cubic centimeter factor of 8.174691e-9.
Simple example
1 st/yd3 × 8.174691e-9 = 8.174691e-9 long ton/cm3
1 stone per cubic yard = 8.174691e-9 long tons per cubic centimeter.
Real-world example
1,000 st/yd3 × 8.174691e-9 = 0.0000081747 long ton/cm3
1,000 stones per cubic yard = 0.0000081747 long tons per cubic centimeter.

Multiply the stone per cubic yard value by 8.174691e-9. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cubic centimeter back to stone per cubic yard?
Use the reverse factor: 1 long ton per cubic centimeter equals 122,328,777.3 stones per cubic yard. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per cubic yard?
Stone per Cubic yard (st/yd3) is a unit of density.
What is a long ton per cubic centimeter?
Long ton per Cubic Centimeter (long ton/cm3) is a unit of density.
Is the stone per cubic yard to long ton per cubic centimeter conversion exact?
Yes. Both stone per cubic yard and long ton per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 8.174691e-9 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
