About Converting Grains per Cubic yard to Short tons per Cubic foot
Grain per Cubic yard and Short ton per Cubic foot 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
short tons per cubic foot = grains per cubic yard × 2.645503e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic yard equals 0.0000847537744654 base units, and 1 short ton per cubic foot equals 32036.9267479 base units, so dividing one by the other gives the direct grain per cubic yard-to-short ton per cubic foot factor of 2.645503e-9.
Simple example
1 gr/yd3 × 2.645503e-9 = 2.645503e-9 ton/ft3
1 grain per cubic yard = 2.645503e-9 short tons per cubic foot.
Real-world example
1,000 gr/yd3 × 2.645503e-9 = 0.0000026455 ton/ft3
1,000 grains per cubic yard = 0.0000026455 short tons per cubic foot.

How do I convert short ton per cubic foot back to grain per cubic yard?
Use the reverse factor: 1 short ton per cubic foot equals 378,000,000 grains per cubic yard. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic yard?
Grain per Cubic yard (gr/yd3) is a unit of density.
What is a short ton per cubic foot?
Short ton per Cubic foot (ton/ft3) is a unit of density.
Is the grain per cubic yard to short ton per cubic foot conversion exact?
Yes. Both grain per cubic yard and short ton per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 2.645503e-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.
