About Converting Stones per Cubic Meter to Pounds per Cubic yard
Stone per Cubic Meter and Pound 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
pounds per cubic yard = stones per cubic meter × 10.7037680118
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cubic meter equals 6.35029318 base units, and 1 pound per cubic yard equals 0.593276421258 base units, so dividing one by the other gives the direct stone per cubic meter-to-pound per cubic yard factor of 10.7037680118.
Simple example
1 st/m3 × 10.70376801 = 10.70376801 lb/yd3
1 stone per cubic meter = 10.70376801 pounds per cubic yard.
Real-world example
1,000 st/m3 × 10.70376801 = 10,703.76801 lb/yd3
1,000 stones per cubic meter = 10,703.76801 pounds per cubic yard.

What is a stone per cubic meter?
Stone per Cubic Meter (st/m3) is a unit of density.
What is a pound per cubic yard?
Pound per Cubic yard (lb/yd3) is a unit of density.
Is the stone per cubic meter to pound per cubic yard conversion exact?
Yes. Both stone per cubic meter and pound per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 10.70376801 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.
