About Converting Grains per Cubic Millimeter to Troy ounces per Teaspoon
Grain per Cubic Millimeter and Troy ounce per Teaspoon 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
troy ounces per teaspoon = grains per cubic millimeter × 10.2685866536
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic millimeter equals 64798.91 base units, and 1 troy ounce per teaspoon equals 6310.40202373 base units, so dividing one by the other gives the direct grain per cubic millimeter-to-troy ounce per teaspoon factor of 10.2685866536.
Simple example
1 gr/mm3 × 10.26858665 = 10.26858665 oz t/tsp
1 grain per cubic millimeter = 10.26858665 troy ounces per teaspoon.
Real-world example
1,000 gr/mm3 × 10.26858665 = 10,268.58665 oz t/tsp
1,000 grains per cubic millimeter = 10,268.58665 troy ounces per teaspoon.

Multiply the grain per cubic millimeter value by 10.26858665. The converter above does this instantly to whatever precision you set.
How do I convert troy ounce per teaspoon back to grain per cubic millimeter?
Use the reverse factor: 1 troy ounce per teaspoon equals 0.0973843854 grains per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic millimeter?
Grain per Cubic Millimeter (gr/mm3) is a unit of density.
What is a troy ounce per teaspoon?
Troy ounce per Teaspoon (oz t/tsp) is a unit of density.
Is the grain per cubic millimeter to troy ounce per teaspoon conversion exact?
Yes. Both grain per cubic millimeter and troy ounce per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 10.26858665 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.
