About Converting Ounces per Pint to Pounds per Milliliter
Ounce per Pint and Pound per Milliliter 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 milliliter = ounces per pint × 0.000132086026179
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 pound per milliliter equals 453592.37 base units, so dividing one by the other gives the direct ounce per pint-to-pound per milliliter factor of 0.000132086026179.
Simple example
1 oz/pt × 0.0001320860262 = 0.000132086 lb/mL
1 ounce per pint = 0.000132086 pounds per milliliter.
Real-world example
1,000 oz/pt × 0.0001320860262 = 0.1320860262 lb/mL
1,000 ounces per pint = 0.1320860262 pounds per milliliter.

Frequently asked questions
How many pounds per milliliter are in 1 ounce per pint?
1 ounce per pint equals 0.000132086 pounds per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per pint to pound per milliliter?
Multiply the ounce per pint value by 0.0001320860262. The converter above does this instantly to whatever precision you set.
How do I convert pound per milliliter back to ounce per pint?

What is a ounce per pint?
Ounce per Pint (oz/pt) is a unit of density.
What is a pound per milliliter?
Pound per Milliliter (lb/mL) is a unit of density.
Is the ounce per pint to pound per milliliter conversion exact?
Yes. Both ounce per pint and pound per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.0001320860262 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.
