About Converting Hectograms per Imperial gallon to Pounds per Cubic Meter
Hectogram per Imperial gallon and Pound per Cubic Meter 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 cubic meter = hectograms per imperial gallon × 48.4949180911
This factor comes from each unit's defined relationship to the category's base unit: 1 hectogram per imperial gallon equals 21.9969248299 base units, and 1 pound per cubic meter equals 0.45359237 base units, so dividing one by the other gives the direct hectogram per imperial gallon-to-pound per cubic meter factor of 48.4949180911.
Simple example
1 hg/imp gal × 48.49491809 = 48.49491809 lb/m3
1 hectogram per imperial gallon = 48.49491809 pounds per cubic meter.
Real-world example
1,000 hg/imp gal × 48.49491809 = 48,494.91809 lb/m3
1,000 hectograms per imperial gallon = 48,494.91809 pounds per cubic meter.

Frequently asked questions
How many pounds per cubic meter are in 1 hectogram per imperial gallon?
1 hectogram per imperial gallon equals 48.49491809 pounds per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert hectogram per imperial gallon to pound per cubic meter?
Multiply the hectogram per imperial gallon value by 48.49491809. The converter above does this instantly to whatever precision you set.
How do I convert pound per cubic meter back to hectogram per imperial gallon?
Use the reverse factor: 1 pound per cubic meter equals 0.0206207174 hectograms per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectogram per imperial gallon?
Hectogram per Imperial gallon (hg/imp gal) is a unit of density.
What is a pound per cubic meter?
Pound per Cubic Meter (lb/m3) is a unit of density.
Is the hectogram per imperial gallon to pound per cubic meter conversion exact?
Yes. Both hectogram per imperial gallon and pound per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 48.49491809 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.
