About Converting Troy ounces per Gallon to Grains per Liter
Troy ounce per Gallon and Grain per Liter 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 liter = troy ounces per gallon × 126.802585132
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 grain per liter equals 0.06479891 base units, so dividing one by the other gives the direct troy ounce per gallon-to-grain per liter factor of 126.802585132.
Simple example
1 oz t/gal × 126.8025851 = 126.8025851 gr/L
1 troy ounce per gallon = 126.8025851 grains per liter.
Real-world example
1,000 oz t/gal × 126.8025851 = 126,802.5851 gr/L
1,000 troy ounces per gallon = 126,802.5851 grains per liter.

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