About Converting Drams per Pint to Pounds per Pint
Dram per Pint and Pound 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
pounds per pint = drams per pint × 0.00390625
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per pint equals 3.74457585365 base units, and 1 pound per pint equals 958.611418535 base units, so dividing one by the other gives the direct dram per pint-to-pound per pint factor of 0.00390625.
Simple example
1 dr/pt × 0.00390625 = 0.00390625 lb/pt
1 dram per pint = 0.00390625 pounds per pint.
Real-world example
1,000 dr/pt × 0.00390625 = 3.90625 lb/pt
1,000 drams per pint = 3.90625 pounds per pint.

How do I convert pound per pint back to dram per pint?
Use the reverse factor: 1 pound per pint equals 256 drams per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per pint?
Dram per Pint (dr/pt) is a unit of density.
What is a pound per pint?
Pound per Pint (lb/pt) is a unit of density.
Is the dram per pint to pound per pint conversion exact?
Yes. Both dram per pint and pound per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.00390625 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.
