About Converting Kilograms per Cubic foot to Kilograms per Cubic yard
Kilogram 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. Kilogram per Cubic foot is most often used for can be used to express the density of construction and bulk materials such as insulation, soil, or aggregate — in practice, pounds per cubic foot (us) or tons per cubic yard are the units more commonly seen in us construction references.
Formula
kilograms per cubic yard = kilograms per cubic foot × 27
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic foot equals 35.3146667215 base units, and 1 kilogram per cubic yard equals 1.30795061931 base units, so dividing one by the other gives the direct kilogram per cubic foot-to-kilogram per cubic yard factor of 27.
Simple example
1 kg/ft3 × 27 = 27 kg/yd3
1 kilogram per cubic foot = 27 kilograms per cubic yard.
Real-world example
1,000 kg/ft3 × 27 = 27,000 kg/yd3
1,000 kilograms per cubic foot = 27,000 kilograms per cubic yard.

Multiply the kilogram per cubic foot value by 27. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per cubic yard back to kilogram per cubic foot?
Use the reverse factor: 1 kilogram per cubic yard equals 0.037037037 kilograms per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilogram per cubic foot?
Kilogram per Cubic foot (kg/ft3) measures density. A mathematically valid way to express density in kilograms per cubic foot. It is classified as a mixed metric/US customary density unit.
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.
Is the kilogram per cubic foot to kilogram per cubic yard conversion exact?
Yes. Both kilogram per cubic foot and kilogram per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 27 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.
