Is the gram per cubic foot to kilogram per cubic yard conversion exact?

Yes. Both gram per cubic foot and kilogram per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 0.027 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.

Q: 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.

Q: What is a kilogram per cubic yard?

Kilogram per Cubic yard (kg/yd3) measures density. A mathematically valid way to express bulk material density in kilograms per cubic yard. It is classified as a mixed metric/US customary density unit.

About Converting Grams per Cubic foot to Kilograms per Cubic yard

Gram per Cubic foot and Kilogram per Cubic yard 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 cubic yard = grams per cubic foot × 0.027

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 cubic yard equals 1.30795061931 base units, so dividing one by the other gives the direct gram per cubic foot-to-kilogram per cubic yard factor of 0.027.

Simple example

1 g/ft3 × 0.027 = 0.027 kg/yd3

1 gram per cubic foot = 0.027 kilograms per cubic yard.

Real-world example

1,000 g/ft3 × 0.027 = 27 kg/yd3

1,000 grams per cubic foot = 27 kilograms per cubic yard.
