About Converting Grams per Imperial gallon to Grams per Cubic foot
Gram per Imperial 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 = grams per imperial gallon × 6.22883545904
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per imperial gallon equals 0.219969248299 base units, and 1 gram per cubic foot equals 0.0353146667215 base units, so dividing one by the other gives the direct gram per imperial gallon-to-gram per cubic foot factor of 6.22883545904.
Simple example
1 g/imp gal × 6.228835459 = 6.228835459 g/ft3
1 gram per imperial gallon = 6.228835459 grams per cubic foot.
Real-world example
1,000 g/imp gal × 6.228835459 = 6,228.835459 g/ft3
1,000 grams per imperial gallon = 6,228.835459 grams per cubic foot.

Understanding the Gram per Imperial gallon (g/imp 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
Gram per Cubic foot — sources
- BIPM SI Brochure — Gram and cubic foot as units combinable to express density, though not a standard industry pairing for general materials.

Frequently asked questions
How many grams per cubic foot are in 1 gram per imperial gallon?
1 gram per imperial gallon equals 6.228835459 grams per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert gram per imperial gallon to gram per cubic foot?
Multiply the gram per imperial gallon value by 6.228835459. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic foot back to gram per imperial gallon?
Use the reverse factor: 1 gram per cubic foot equals 0.1605436532 grams per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp 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 gram per imperial gallon to gram per cubic foot conversion exact?
Yes. Both gram per imperial gallon and gram per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 6.228835459 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.
