About Converting Troy ounces per Liter to Grains per Gallon
Troy ounce per Liter and Grain per Gallon 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
grains per gallon = troy ounces per liter × 1816.99765632
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per liter equals 31.1034768 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct troy ounce per liter-to-grain per gallon factor of 1816.99765632.
Simple example
1 oz t/L × 1816.997656 = 1,816.997656 gr/gal
1 troy ounce per liter = 1,816.997656 grains per gallon.
Real-world example
1,000 oz t/L × 1816.997656 = 1,816,997.656 gr/gal
1,000 troy ounces per liter = 1,816,997.656 grains per gallon.

What is a troy ounce per liter?
Troy ounce per Liter (oz t/L) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the troy ounce per liter to grain per gallon conversion exact?
