About Converting Grains per Teaspoon to Ounces per Tablespoon
Grain per Teaspoon and Ounce per Tablespoon 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 tablespoon = grains per teaspoon × 0.00685714285714
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 tablespoon equals 1917.22283707 base units, so dividing one by the other gives the direct grain per teaspoon-to-ounce per tablespoon factor of 0.00685714285714.
Simple example
1 gr/tsp × 0.006857142857 = 0.0068571429 oz/tbsp
1 grain per teaspoon = 0.0068571429 ounces per tablespoon.
Real-world example
1,000 gr/tsp × 0.006857142857 = 6.857142857 oz/tbsp
1,000 grains per teaspoon = 6.857142857 ounces per tablespoon.

What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a ounce per tablespoon?
Ounce per Tablespoon (oz/tbsp) is a unit of density.
Is the grain per teaspoon to ounce per tablespoon conversion exact?
Yes. Both grain per teaspoon and ounce per tablespoon are defined by fixed standards rather than physical artifacts, so the factor of 0.006857142857 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.
