About Converting Hectograms per Liter to Pounds per Imperial gallon
Hectogram per Liter and Pound per Imperial 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
pounds per imperial gallon = hectograms per liter × 1.0022412855
This factor comes from each unit's defined relationship to the category's base unit: 1 hectogram per liter equals 100 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct hectogram per liter-to-pound per imperial gallon factor of 1.0022412855.
Simple example
1 hg/L × 1.002241285 = 1.002241285 lb/imp gal
1 hectogram per liter = 1.002241285 pounds per imperial gallon.
Real-world example
1,000 hg/L × 1.002241285 = 1,002.241285 lb/imp gal
1,000 hectograms per liter = 1,002.241285 pounds per imperial gallon.

Multiply the hectogram per liter value by 1.002241285. The converter above does this instantly to whatever precision you set.
How do I convert pound per imperial gallon back to hectogram per liter?
Use the reverse factor: 1 pound per imperial gallon equals 0.9977637266 hectograms per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectogram per liter?
Hectogram per Liter (hg/L) is a unit of density.
What is a pound per imperial gallon?
Pound per Imperial gallon (lb/imp gal) is a unit of density.
Is the hectogram per liter to pound per imperial gallon conversion exact?
Yes. Both hectogram per liter and pound per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.002241285 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.
