About Converting Grains per Teaspoon to Ounces per Cup
Grain per Teaspoon and Ounce per Cup 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 cup = grains per teaspoon × 0.109714285714
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 cup equals 119.826427317 base units, so dividing one by the other gives the direct grain per teaspoon-to-ounce per cup factor of 0.109714285714.
Simple example
1 gr/tsp × 0.1097142857 = 0.1097142857 oz/cup
1 grain per teaspoon = 0.1097142857 ounces per cup.
Real-world example
1,000 gr/tsp × 0.1097142857 = 109.7142857 oz/cup
1,000 grains per teaspoon = 109.7142857 ounces per cup.

What is a grain per teaspoon?
Grain per Teaspoon (gr/tsp) is a unit of density.
What is a ounce per cup?
Ounce per Cup (oz/cup) is a unit of density.
Is the grain per teaspoon to ounce per cup conversion exact?
