About Converting Grains per Teaspoon to Pounds per Cubic Centimeter
Grain per Teaspoon and Pound 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
pounds per cubic centimeter = grains per teaspoon × 0.0000289834480302
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 pound per cubic centimeter equals 453592.37 base units, so dividing one by the other gives the direct grain per teaspoon-to-pound per cubic centimeter factor of 0.0000289834480302.
Simple example
1 gr/tsp × 0.00002898344803 = 0.0000289834 lb/cm3
1 grain per teaspoon = 0.0000289834 pounds per cubic centimeter.
Real-world example
1,000 gr/tsp × 0.00002898344803 = 0.028983448 lb/cm3
1,000 grains per teaspoon = 0.028983448 pounds per cubic centimeter.

Frequently asked questions
How many pounds per cubic centimeter are in 1 grain per teaspoon?
1 grain per teaspoon equals 0.0000289834 pounds per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per teaspoon to pound per cubic centimeter?
Multiply the grain per teaspoon value by 0.00002898344803. The converter above does this instantly to whatever precision you set.
How do I convert pound per cubic centimeter back to grain per teaspoon?
Use the reverse factor: 1 pound per cubic centimeter equals 34,502.45116 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 pound per cubic centimeter?
Pound per Cubic Centimeter (lb/cm3) is a unit of density.
Is the grain per teaspoon to pound per cubic centimeter conversion exact?
Yes. Both grain per teaspoon and pound per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.00002898344803 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.
