About Converting Ounces per Imperial gallon to Pounds per Milliliter
Ounce per Imperial gallon and Pound per Milliliter 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
pounds per milliliter = ounces per imperial gallon × 0.0000137480780187
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per imperial gallon equals 6.23602329144 base units, and 1 pound per milliliter equals 453592.37 base units, so dividing one by the other gives the direct ounce per imperial gallon-to-pound per milliliter factor of 0.0000137480780187.
Simple example
1 oz/imp gal × 0.00001374807802 = 0.0000137481 lb/mL
1 ounce per imperial gallon = 0.0000137481 pounds per milliliter.
Real-world example
1,000 oz/imp gal × 0.00001374807802 = 0.013748078 lb/mL
1,000 ounces per imperial gallon = 0.013748078 pounds per milliliter.

What is a ounce per imperial gallon?
Ounce per Imperial gallon (oz/imp gal) is a unit of density.
What is a pound per milliliter?
Pound per Milliliter (lb/mL) is a unit of density.
Is the ounce per imperial gallon to pound per milliliter conversion exact?
Yes. Both ounce per imperial gallon and pound per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.00001374807802 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
