About Converting Troy ounces per Gallon to Milligrams per Teaspoon
Troy ounce per Gallon and Milligram 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
milligrams per teaspoon = troy ounces per gallon × 40.49931875
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per gallon equals 8.21666930173 base units, and 1 milligram per teaspoon equals 0.202884136211 base units, so dividing one by the other gives the direct troy ounce per gallon-to-milligram per teaspoon factor of 40.49931875.
Simple example
1 oz t/gal × 40.49931875 = 40.49931875 mg/tsp
1 troy ounce per gallon = 40.49931875 milligrams per teaspoon.
Real-world example
1,000 oz t/gal × 40.49931875 = 40,499.31875 mg/tsp
1,000 troy ounces per gallon = 40,499.31875 milligrams per teaspoon.
