About Converting Pounds per Cubic foot to Kilograms per Pint
Pound per Cubic foot and Kilogram per Pint 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. Pound per Cubic foot is most often used for us construction material density specs (concrete, soil, lumber, insulation).
Formula
kilograms per pint = pounds per cubic foot × 0.00757956000217
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic foot equals 16.018463374 base units, and 1 kilogram per pint equals 2113.37641887 base units, so dividing one by the other gives the direct pound per cubic foot-to-kilogram per pint factor of 0.00757956000217.
Simple example
1 lb/ft3 × 0.007579560002 = 0.00757956 kg/pt
1 pound per cubic foot = 0.00757956 kilograms per pint.
Real-world example
1,000 lb/ft3 × 0.007579560002 = 7.579560002 kg/pt
1,000 pounds per cubic foot = 7.579560002 kilograms per pint.

Frequently asked questions
How many kilograms per pint are in 1 pound per cubic foot?
1 pound per cubic foot equals 0.00757956 kilograms per pint, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cubic foot to kilogram per pint?
Multiply the pound per cubic foot value by 0.007579560002. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per pint back to pound per cubic foot?
Use the reverse factor: 1 kilogram per pint equals 131.9337798 pounds per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cubic foot?
Pound per Cubic foot (lb/ft3) measures density. The US customary unit for expressing density, commonly used in construction and engineering material specifications. It is classified as a US customary density unit.
What is a kilogram per pint?
Kilogram per Pint (kg/pt) is a unit of density.
Is the pound per cubic foot to kilogram per pint conversion exact?
Yes. Both pound per cubic foot and kilogram per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.007579560002 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.
