About Converting Kilograms per Cubic foot to Pounds per Cubic Centimeter
Kilogram per Cubic foot and Pound per Cubic Centimeter 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
pounds per cubic centimeter = kilograms per cubic foot × 0.0000778555131372
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 pound per cubic centimeter equals 453592.37 base units, so dividing one by the other gives the direct kilogram per cubic foot-to-pound per cubic centimeter factor of 0.0000778555131372.
Simple example
1 kg/ft3 × 0.00007785551314 = 0.0000778555 lb/cm3
1 kilogram per cubic foot = 0.0000778555 pounds per cubic centimeter.
Real-world example
1,000 kg/ft3 × 0.00007785551314 = 0.0778555131 lb/cm3
1,000 kilograms per cubic foot = 0.0778555131 pounds per cubic centimeter.

Frequently asked questions
How many pounds per cubic centimeter are in 1 kilogram per cubic foot?
1 kilogram per cubic foot equals 0.0000778555 pounds per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert kilogram per cubic foot to pound per cubic centimeter?
Multiply the kilogram per cubic foot value by 0.00007785551314. The converter above does this instantly to whatever precision you set.
How do I convert pound per cubic centimeter back to kilogram per cubic foot?
Use the reverse factor: 1 pound per cubic centimeter equals 12,844.30556 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 pound per cubic centimeter?
Pound per Cubic Centimeter (lb/cm3) is a unit of density.
Is the kilogram per cubic foot to pound per cubic centimeter conversion exact?
Yes. Both kilogram per cubic foot and pound per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.00007785551314 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.
