About Converting Ounces per Quart to Pounds per Milliliter
Ounce per Quart 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 quart × 0.0000660430130895
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per quart equals 29.9566068292 base units, and 1 pound per milliliter equals 453592.37 base units, so dividing one by the other gives the direct ounce per quart-to-pound per milliliter factor of 0.0000660430130895.
Simple example
1 oz/qt × 0.00006604301309 = 0.000066043 lb/mL
1 ounce per quart = 0.000066043 pounds per milliliter.
Real-world example
1,000 oz/qt × 0.00006604301309 = 0.0660430131 lb/mL
1,000 ounces per quart = 0.0660430131 pounds per milliliter.

What is a ounce per quart?
Ounce per Quart (oz/qt) 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 quart to pound per milliliter conversion exact?
Yes. Both ounce per quart and pound per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.00006604301309 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.
