About Converting Stones per Cubic foot to Metric tons per Cubic yard
Stone per Cubic foot and Metric ton 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
metric tons per cubic yard = stones per cubic foot × 0.17145791586
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cubic foot equals 224.258487235 base units, and 1 metric ton per cubic yard equals 1307.95061931 base units, so dividing one by the other gives the direct stone per cubic foot-to-metric ton per cubic yard factor of 0.17145791586.
Simple example
1 st/ft3 × 0.1714579159 = 0.1714579159 t/yd3
1 stone per cubic foot = 0.1714579159 metric tons per cubic yard.
Real-world example
1,000 st/ft3 × 0.1714579159 = 171.4579159 t/yd3
1,000 stones per cubic foot = 171.4579159 metric tons per cubic yard.

Multiply the stone per cubic foot value by 0.1714579159. The converter above does this instantly to whatever precision you set.
How do I convert metric ton per cubic yard back to stone per cubic foot?
Use the reverse factor: 1 metric ton per cubic yard equals 5.832334978 stones per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per cubic foot?
Stone per Cubic foot (st/ft3) is a unit of density.
What is a metric ton per cubic yard?
Metric ton per Cubic yard (t/yd3) is a unit of density.
Is the stone per cubic foot to metric ton per cubic yard conversion exact?
Yes. Both stone per cubic foot and metric ton per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 0.1714579159 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.
