About Converting Grains per Teaspoon to Kilograms per Cubic yard
Grain per Teaspoon and Kilogram 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
kilograms per cubic yard = grains per teaspoon × 10.0513510897
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per teaspoon equals 13.1466708828 base units, and 1 kilogram per cubic yard equals 1.30795061931 base units, so dividing one by the other gives the direct grain per teaspoon-to-kilogram per cubic yard factor of 10.0513510897.
Simple example
1 gr/tsp × 10.05135109 = 10.05135109 kg/yd3
1 grain per teaspoon = 10.05135109 kilograms per cubic yard.
Real-world example
1,000 gr/tsp × 10.05135109 = 10,051.35109 kg/yd3
1,000 grains per teaspoon = 10,051.35109 kilograms per cubic yard.

Frequently asked questions
How many kilograms per cubic yard are in 1 grain per teaspoon?
1 grain per teaspoon equals 10.05135109 kilograms per cubic yard, using the exact defined conversion factor rather than an estimate.
How do I convert grain per teaspoon to kilogram per cubic yard?
Multiply the grain per teaspoon value by 10.05135109. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per cubic yard back to grain per teaspoon?
Use the reverse factor: 1 kilogram per cubic yard equals 0.0994891126 grains per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a kilogram per cubic yard?
Kilogram per Cubic yard (kg/yd3) measures density. A mathematically valid way to express bulk material density in kilograms per cubic yard. It is classified as a mixed metric/US customary density unit.
Is the grain per teaspoon to kilogram per cubic yard conversion exact?
Yes. Both grain per teaspoon and kilogram per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 10.05135109 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.
