About Converting Grams per Cubic foot to Kilograms per Imperial gallon
Gram per Cubic foot and Kilogram per Imperial gallon 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. Gram per Cubic foot is most often used for 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.
Formula
kilograms per imperial gallon = grams per cubic foot × 0.000160543653236
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic foot equals 0.0353146667215 base units, and 1 kilogram per imperial gallon equals 219.969248299 base units, so dividing one by the other gives the direct gram per cubic foot-to-kilogram per imperial gallon factor of 0.000160543653236.
Simple example
1 g/ft3 × 0.0001605436532 = 0.0001605437 kg/imp gal
1 gram per cubic foot = 0.0001605437 kilograms per imperial gallon.
Real-world example
1,000 g/ft3 × 0.0001605436532 = 0.1605436532 kg/imp gal
1,000 grams per cubic foot = 0.1605436532 kilograms per imperial gallon.

Gram per Cubic foot vs. Kilogram per Imperial gallon
| Aspect | Gram per Cubic foot | Kilogram per Imperial gallon |
|---|---|---|
| Family | mixed metric/US customary density unit | mixed metric/UK customary density unit |
| Typical use | 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 | Can be used to express liquid density in UK/Commonwealth contexts that reference the imperial gallon — in practice, kilograms per liter is the more commonly seen metric density unit even in these regions |
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
Understanding the Kilogram per Imperial gallon
Kilogram per Imperial gallon (kg/imp gal) measures density. A mathematically valid way to express liquid density in kilograms per imperial gallon. It is classified as a mixed metric/UK customary density unit.
Uses of the Kilogram per Imperial gallon today
- Can be used to express liquid density in UK/Commonwealth contexts that reference the imperial gallon — in practice, kilograms per liter is the more commonly seen metric density unit even in these regions
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.
Kilogram per Imperial gallon — sources
- UK/Commonwealth liquid-measurement references — The imperial gallon remains in some UK/Commonwealth commercial use, but liquid density is more commonly quoted in kilograms per liter.

Frequently asked questions
How many kilograms per imperial gallon are in 1 gram per cubic foot?
1 gram per cubic foot equals 0.0001605437 kilograms per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic foot to kilogram per imperial gallon?
Multiply the gram per cubic foot value by 0.0001605436532. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per imperial gallon back to gram per cubic foot?
Use the reverse factor: 1 kilogram per imperial gallon equals 6,228.835459 grams per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
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.
What is a kilogram per imperial gallon?
Kilogram per Imperial gallon (kg/imp gal) measures density. A mathematically valid way to express liquid density in kilograms per imperial gallon. It is classified as a mixed metric/UK customary density unit.
Is the gram per cubic foot to kilogram per imperial gallon conversion exact?
Yes. Both gram per cubic foot and kilogram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.0001605436532 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.
