About Converting Grains per Teaspoon to Ounces per Teaspoon
Grain per Teaspoon and 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
ounces per teaspoon = grains per teaspoon × 0.00228571428571
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 ounce per teaspoon equals 5751.66851121 base units, so dividing one by the other gives the direct grain per teaspoon-to-ounce per teaspoon factor of 0.00228571428571.
Simple example
1 gr/tsp × 0.002285714286 = 0.0022857143 oz/tsp
1 grain per teaspoon = 0.0022857143 ounces per teaspoon.
Real-world example
1,000 gr/tsp × 0.002285714286 = 2.285714286 oz/tsp
1,000 grains per teaspoon = 2.285714286 ounces per teaspoon.

Multiply the grain per teaspoon value by 0.002285714286. The converter above does this instantly to whatever precision you set.
How do I convert ounce per teaspoon back to grain per teaspoon?
Use the reverse factor: 1 ounce per teaspoon equals 437.5 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 ounce per teaspoon?
Ounce per Teaspoon (oz/tsp) is a unit of density.
Is the grain per teaspoon to ounce per teaspoon conversion exact?
Yes. Both grain per teaspoon and ounce per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.002285714286 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.
