About Converting Grains per Tablespoon to Troy ounces per Quart
Grain per Tablespoon and Troy ounce per Quart 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 quart = grains per tablespoon × 0.133333333333
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per tablespoon equals 4.38222362759 base units, and 1 troy ounce per quart equals 32.8666772069 base units, so dividing one by the other gives the direct grain per tablespoon-to-troy ounce per quart factor of 0.133333333333.
Simple example
1 gr/tbsp × 0.1333333333 = 0.1333333333 oz t/qt
1 grain per tablespoon = 0.1333333333 troy ounces per quart.
Real-world example
1,000 gr/tbsp × 0.1333333333 = 133.3333333 oz t/qt
1,000 grains per tablespoon = 133.3333333 troy ounces per quart.
