About Converting Long tons per Cubic yard to Grains per Cubic Centimeter
Long ton per Cubic yard and Grain per Cubic Centimeter 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
grains per cubic centimeter = long tons per cubic yard × 20.5086657108
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cubic yard equals 1328.93918362 base units, and 1 grain per cubic centimeter equals 64.79891 base units, so dividing one by the other gives the direct long ton per cubic yard-to-grain per cubic centimeter factor of 20.5086657108.
Simple example
1 long ton/yd3 × 20.50866571 = 20.50866571 gr/cm3
1 long ton per cubic yard = 20.50866571 grains per cubic centimeter.
Real-world example
1,000 long ton/yd3 × 20.50866571 = 20,508.66571 gr/cm3
1,000 long tons per cubic yard = 20,508.66571 grains per cubic centimeter.

Multiply the long ton per cubic yard value by 20.50866571. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic centimeter back to long ton per cubic yard?
Use the reverse factor: 1 grain per cubic centimeter equals 0.0487598762 long tons per cubic yard. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per cubic yard?
Long ton per Cubic yard (long ton/yd3) is a unit of density.
What is a grain per cubic centimeter?
Grain per Cubic Centimeter (gr/cm3) is a unit of density.
Is the long ton per cubic yard to grain per cubic centimeter conversion exact?
Yes. Both long ton per cubic yard and grain per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 20.50866571 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.
