About Converting Kilograms per Cubic yard to Grams per Cubic foot
Kilogram per Cubic yard 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. Kilogram per Cubic yard is most often used for can be used to express the density of bulk construction materials such as gravel, soil, or aggregate — in practice, us construction and landscaping references more commonly express this as tons per cubic yard or pounds per cubic foot.
Formula
grams per cubic foot = kilograms per cubic yard × 37.037037037
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic yard equals 1.30795061931 base units, and 1 gram per cubic foot equals 0.0353146667215 base units, so dividing one by the other gives the direct kilogram per cubic yard-to-gram per cubic foot factor of 37.037037037.
Simple example
1 kg/yd3 × 37.03703704 = 37.03703704 g/ft3
1 kilogram per cubic yard = 37.03703704 grams per cubic foot.
Real-world example
1,000 kg/yd3 × 37.03703704 = 37,037.03704 g/ft3
1,000 kilograms per cubic yard = 37,037.03704 grams per cubic foot.

Kilogram per Cubic yard vs. Gram per Cubic foot
| Aspect | Kilogram per Cubic yard | Gram per Cubic foot |
|---|---|---|
| Family | mixed metric/US customary density unit | mixed metric/US customary density unit |
| Typical use | Can be used to express the density of bulk construction materials such as gravel, soil, or aggregate — in practice, US construction and landscaping references more commonly express this as tons per cubic yard or pounds per cubic foot | 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 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.
Uses of the Kilogram per Cubic yard today
- Can be used to express the density of bulk construction materials such as gravel, soil, or aggregate — in practice, US construction and landscaping references more commonly express this as tons per cubic yard or pounds per cubic foot
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.

Frequently asked questions
How many grams per cubic foot are in 1 kilogram per cubic yard?
1 kilogram per cubic yard equals 37.03703704 grams per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert kilogram per cubic yard to gram per cubic foot?
Multiply the kilogram per cubic yard value by 37.03703704. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic foot back to kilogram per cubic yard?
Use the reverse factor: 1 gram per cubic foot equals 0.027 kilograms per cubic yard. You can also use the swap control in the converter above to flip the direction instantly.
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.
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 kilogram per cubic yard to gram per cubic foot conversion exact?
Yes. Both kilogram per cubic yard and gram per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 37.03703704 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.
