About Converting Pounds per Cup to Kilograms per Pint
Pound per Cup 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. Both are mass per volume density units.
Formula
kilograms per pint = pounds per cup × 0.90718474
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cup equals 1917.22283707 base units, and 1 kilogram per pint equals 2113.37641887 base units, so dividing one by the other gives the direct pound per cup-to-kilogram per pint factor of 0.90718474.
Simple example
1 lb/cup × 0.90718474 = 0.90718474 kg/pt
1 pound per cup = 0.90718474 kilograms per pint.
Real-world example
1,000 lb/cup × 0.90718474 = 907.18474 kg/pt
1,000 pounds per cup = 907.18474 kilograms per pint.

Frequently asked questions
How many kilograms per pint are in 1 pound per cup?
1 pound per cup equals 0.90718474 kilograms per pint, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cup to kilogram per pint?
Multiply the pound per cup value by 0.90718474. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per pint back to pound per cup?
Use the reverse factor: 1 kilogram per pint equals 1.102311311 pounds per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cup?
Pound per Cup (lb/cup) is a unit of density.
What is a kilogram per pint?
Kilogram per Pint (kg/pt) is a unit of density.
Is the pound per cup to kilogram per pint conversion exact?
Yes. Both pound per cup and kilogram per pint 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.
