About Converting Pounds per Pint to Kilograms per Quart
Pound per Pint and Kilogram per Quart 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. Both are mass per volume density units.
Formula
kilograms per quart = pounds per pint × 0.90718474
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per pint equals 958.611418535 base units, and 1 kilogram per quart equals 1056.68820943 base units, so dividing one by the other gives the direct pound per pint-to-kilogram per quart factor of 0.90718474.
Simple example
1 lb/pt × 0.90718474 = 0.90718474 kg/qt
1 pound per pint = 0.90718474 kilograms per quart.
Real-world example
1,000 lb/pt × 0.90718474 = 907.18474 kg/qt
1,000 pounds per pint = 907.18474 kilograms per quart.

Multiply the pound per pint value by 0.90718474. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per quart back to pound per pint?
Use the reverse factor: 1 kilogram per quart equals 1.102311311 pounds per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per pint?
Pound per Pint (lb/pt) is a unit of density.
What is a kilogram per quart?
Kilogram per Quart (kg/qt) is a unit of density.
Is the pound per pint to kilogram per quart conversion exact?
Yes. Both pound per pint and kilogram per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.90718474 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.
