About Converting Hectograms per Gallon to Pounds per Cubic Meter
Hectogram per 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 gallon × 58.2399682689
This factor comes from each unit's defined relationship to the category's base unit: 1 hectogram per gallon equals 26.4172052358 base units, and 1 pound per cubic meter equals 0.45359237 base units, so dividing one by the other gives the direct hectogram per gallon-to-pound per cubic meter factor of 58.2399682689.
Simple example
1 hg/gal × 58.23996827 = 58.23996827 lb/m3
1 hectogram per gallon = 58.23996827 pounds per cubic meter.
Real-world example
1,000 hg/gal × 58.23996827 = 58,239.96827 lb/m3
1,000 hectograms per gallon = 58,239.96827 pounds per cubic meter.

Frequently asked questions
How many pounds per cubic meter are in 1 hectogram per gallon?
1 hectogram per gallon equals 58.23996827 pounds per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert hectogram per gallon to pound per cubic meter?
Multiply the hectogram per gallon value by 58.23996827. The converter above does this instantly to whatever precision you set.
How do I convert pound per cubic meter back to hectogram per gallon?
Use the reverse factor: 1 pound per cubic meter equals 0.017170339 hectograms per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectogram per gallon?
Hectogram per Gallon (hg/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 gallon to pound per cubic meter conversion exact?
Yes. Both hectogram per gallon and pound per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 58.23996827 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.
