About Converting Ounces per Pint to Drams per Pint
Ounce per Pint and Dram 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
drams per pint = ounces per pint × 16
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per pint equals 59.9132136584 base units, and 1 dram per pint equals 3.74457585365 base units, so dividing one by the other gives the direct ounce per pint-to-dram per pint factor of 16.
Simple example
1 oz/pt × 16 = 16 dr/pt
1 ounce per pint = 16 drams per pint.
Real-world example
1,000 oz/pt × 16 = 16,000 dr/pt
1,000 ounces per pint = 16,000 drams per pint.

Frequently asked questions
How many drams per pint are in 1 ounce per pint?
1 ounce per pint equals 16 drams per pint, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per pint to dram per pint?
Multiply the ounce per pint value by 16. The converter above does this instantly to whatever precision you set.
How do I convert dram per pint back to ounce per pint?
Use the reverse factor: 1 dram per pint equals 0.0625 ounces per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per pint?
Ounce per Pint (oz/pt) is a unit of density.
What is a dram per pint?
Dram per Pint (dr/pt) is a unit of density.
Is the ounce per pint to dram per pint conversion exact?
Yes. Both ounce per pint and dram per pint are defined by fixed standards rather than physical artifacts, so the factor of 16 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.
