About Converting Metric tons per Cubic foot to Stones per Gallon
Metric ton per Cubic foot and Stone per Gallon 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 gallon = metric tons per cubic foot × 21.0510840628
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per cubic foot equals 35314.6667215 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct metric ton per cubic foot-to-stone per gallon factor of 21.0510840628.
Simple example
1 t/ft3 × 21.05108406 = 21.05108406 st/gal
1 metric ton per cubic foot = 21.05108406 stones per gallon.
Real-world example
1,000 t/ft3 × 21.05108406 = 21,051.08406 st/gal
1,000 metric tons per cubic foot = 21,051.08406 stones per gallon.

How do I convert stone per gallon back to metric ton per cubic foot?
Use the reverse factor: 1 stone per gallon equals 0.0475034918 metric tons per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a metric ton per cubic foot?
Metric ton per Cubic foot (t/ft3) is a unit of density.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the metric ton per cubic foot to stone per gallon conversion exact?
Yes. Both metric ton per cubic foot and stone per gallon are defined by fixed standards rather than physical artifacts, so the factor of 21.05108406 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.
