About Converting Stones per Cubic yard to Metric tons per Cubic Meter
Stone per Cubic yard and Metric ton per Cubic Meter 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 meter = stones per cubic yard × 0.00830586989761
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 metric ton per cubic meter equals 1000 base units, so dividing one by the other gives the direct stone per cubic yard-to-metric ton per cubic meter factor of 0.00830586989761.
Simple example
1 st/yd3 × 0.008305869898 = 0.0083058699 t/m3
1 stone per cubic yard = 0.0083058699 metric tons per cubic meter.
Real-world example
1,000 st/yd3 × 0.008305869898 = 8.305869898 t/m3
1,000 stones per cubic yard = 8.305869898 metric tons per cubic meter.

Frequently asked questions
How many metric tons per cubic meter are in 1 stone per cubic yard?
1 stone per cubic yard equals 0.0083058699 metric tons per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert stone per cubic yard to metric ton per cubic meter?
Multiply the stone per cubic yard value by 0.008305869898. The converter above does this instantly to whatever precision you set.
How do I convert metric ton per cubic meter back to stone per cubic yard?
Use the reverse factor: 1 metric ton per cubic meter equals 120.3967811 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 metric ton per cubic meter?
Metric ton per Cubic Meter (t/m3) is a unit of density.
Is the stone per cubic yard to metric ton per cubic meter conversion exact?
Yes. Both stone per cubic yard and metric ton per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 0.008305869898 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.
