About Converting Ounces per Milliliter to Drams per Pint
Ounce per Milliliter 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 milliliter × 7570.823568
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per milliliter equals 28349.523125 base units, and 1 dram per pint equals 3.74457585365 base units, so dividing one by the other gives the direct ounce per milliliter-to-dram per pint factor of 7570.823568.
Simple example
1 oz/mL × 7570.823568 = 7,570.823568 dr/pt
1 ounce per milliliter = 7,570.823568 drams per pint.
Real-world example
1,000 oz/mL × 7570.823568 = 7,570,823.568 dr/pt
1,000 ounces per milliliter = 7,570,823.568 drams per pint.

Frequently asked questions
How many drams per pint are in 1 ounce per milliliter?
1 ounce per milliliter equals 7,570.823568 drams per pint, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per milliliter to dram per pint?
Multiply the ounce per milliliter value by 7570.823568. The converter above does this instantly to whatever precision you set.
How do I convert dram per pint back to ounce per milliliter?
Use the reverse factor: 1 dram per pint equals 0.000132086 ounces per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per milliliter?
Ounce per Milliliter (oz/mL) 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 milliliter to dram per pint conversion exact?
Yes. Both ounce per milliliter and dram per pint are defined by fixed standards rather than physical artifacts, so the factor of 7570.823568 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.
