About Converting Imperial hundredweights per Gallon to Grams per Cubic foot
Imperial hundredweight per Gallon and Gram per Cubic foot 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
grams per cubic foot = imperial hundredweights per gallon × 380027.93472
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial hundredweight per gallon equals 13420.5598595 base units, and 1 gram per cubic foot equals 0.0353146667215 base units, so dividing one by the other gives the direct imperial hundredweight per gallon-to-gram per cubic foot factor of 380027.93472.
Simple example
1 long cwt/gal × 380027.9347 = 380,027.9347 g/ft3
1 imperial hundredweight per gallon = 380,027.9347 grams per cubic foot.
Real-world example
1,000 long cwt/gal × 380027.9347 = 380,027,934.7 g/ft3
1,000 imperial hundredweights per gallon = 380,027,934.7 grams per cubic foot.

Understanding the Imperial hundredweight per Gallon (long cwt/gal)
Mass per volume density.
Understanding the Gram per Cubic foot
Gram per Cubic foot (g/ft3) measures density. A gram is a small mass unit and a cubic foot a comparatively large volume, so this combination naturally suits low-density materials rather than typical solids or liquids. It is classified as a mixed metric/US customary density unit.
Uses of the Gram per Cubic foot today
- Can be used to express the density of low-density materials such as insulation foam, packaging material, or gas concentration by volume — for typical solid or liquid materials, kilograms per cubic meter or pounds per cubic foot are more commonly encountered

Frequently asked questions
How many grams per cubic foot are in 1 imperial hundredweight per gallon?
1 imperial hundredweight per gallon equals 380,027.9347 grams per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert imperial hundredweight per gallon to gram per cubic foot?
Multiply the imperial hundredweight per gallon value by 380027.9347. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic foot back to imperial hundredweight per gallon?
Use the reverse factor: 1 gram per cubic foot equals 0.0000026314 imperial hundredweights per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial hundredweight per gallon?
Imperial hundredweight per Gallon (long cwt/gal) is a unit of density.
What is a gram per cubic foot?
Gram per Cubic foot (g/ft3) measures density. A gram is a small mass unit and a cubic foot a comparatively large volume, so this combination naturally suits low-density materials rather than typical solids or liquids. It is classified as a mixed metric/US customary density unit.
Is the imperial hundredweight per gallon to gram per cubic foot conversion exact?
Yes. Both imperial hundredweight per gallon and gram per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 380027.9347 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.
