About Converting Pounds per Imperial gallon to Ounces per Gallon
Pound per Imperial gallon and Ounce 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
ounces per gallon = pounds per imperial gallon × 13.3227869541
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 ounce per gallon equals 7.48915170731 base units, so dividing one by the other gives the direct pound per imperial gallon-to-ounce per gallon factor of 13.3227869541.
Simple example
1 lb/imp gal × 13.32278695 = 13.32278695 oz/gal
1 pound per imperial gallon = 13.32278695 ounces per gallon.
Real-world example
1,000 lb/imp gal × 13.32278695 = 13,322.78695 oz/gal
1,000 pounds per imperial gallon = 13,322.78695 ounces per gallon.
