About Converting Grains per Teaspoon to Troy ounces per Milliliter
Grain per Teaspoon and Troy ounce per Milliliter 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 milliliter = grains per teaspoon × 0.000422675283773
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 troy ounce per milliliter equals 31103.4768 base units, so dividing one by the other gives the direct grain per teaspoon-to-troy ounce per milliliter factor of 0.000422675283773.
Simple example
1 gr/tsp × 0.0004226752838 = 0.0004226753 oz t/mL
1 grain per teaspoon = 0.0004226753 troy ounces per milliliter.
Real-world example
1,000 gr/tsp × 0.0004226752838 = 0.4226752838 oz t/mL
1,000 grains per teaspoon = 0.4226752838 troy ounces per milliliter.

What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a troy ounce per milliliter?
Troy ounce per Milliliter (oz t/mL) is a unit of density.
Is the grain per teaspoon to troy ounce per milliliter conversion exact?
Yes. Both grain per teaspoon and troy ounce per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.0004226752838 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.
