About Converting Pounds per Imperial gallon to Hectograms per Cubic Meter
Pound per Imperial gallon and Hectogram 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
hectograms per cubic meter = pounds per imperial gallon × 997.763726631
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 hectogram per cubic meter equals 0.1 base units, so dividing one by the other gives the direct pound per imperial gallon-to-hectogram per cubic meter factor of 997.763726631.
Simple example
1 lb/imp gal × 997.7637266 = 997.7637266 hg/m3
1 pound per imperial gallon = 997.7637266 hectograms per cubic meter.
Real-world example
1,000 lb/imp gal × 997.7637266 = 997,763.7266 hg/m3
1,000 pounds per imperial gallon = 997,763.7266 hectograms per cubic meter.

Frequently asked questions
How many hectograms per cubic meter are in 1 pound per imperial gallon?
1 pound per imperial gallon equals 997.7637266 hectograms per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert pound per imperial gallon to hectogram per cubic meter?
Multiply the pound per imperial gallon value by 997.7637266. The converter above does this instantly to whatever precision you set.
How do I convert hectogram per cubic meter back to pound per imperial gallon?
Use the reverse factor: 1 hectogram per cubic meter equals 0.0010022413 pounds per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per imperial gallon?
Pound per Imperial gallon (lb/imp gal) is a unit of density.
What is a hectogram per cubic meter?
Hectogram per Cubic Meter (hg/m3) is a unit of density.
Is the pound per imperial gallon to hectogram per cubic meter conversion exact?
Yes. Both pound per imperial gallon and hectogram per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 997.7637266 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.
