About Converting Stones per Pint to Kilograms per Pint
Stone per Pint 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 = stones per pint × 6.35029318
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per pint equals 13420.5598595 base units, and 1 kilogram per pint equals 2113.37641887 base units, so dividing one by the other gives the direct stone per pint-to-kilogram per pint factor of 6.35029318.
Simple example
1 st/pt × 6.35029318 = 6.35029318 kg/pt
1 stone per pint = 6.35029318 kilograms per pint.
Real-world example
1,000 st/pt × 6.35029318 = 6,350.29318 kg/pt
1,000 stones per pint = 6,350.29318 kilograms per pint.

Frequently asked questions
How many kilograms per pint are in 1 stone per pint?
1 stone per pint equals 6.35029318 kilograms per pint, using the exact defined conversion factor rather than an estimate.
How do I convert stone per pint to kilogram per pint?
Multiply the stone per pint value by 6.35029318. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per pint back to stone per pint?
Use the reverse factor: 1 kilogram per pint equals 0.1574730444 stones per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per pint?
Stone per Pint (st/pt) is a unit of density.
What is a kilogram per pint?
Kilogram per Pint (kg/pt) is a unit of density.
Is the stone per pint to kilogram per pint conversion exact?
Yes. Both stone per pint and kilogram per pint are defined by fixed standards rather than physical artifacts, so the factor of 6.35029318 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.
