About Converting Ounces per Quart to Kilograms per Milliliter
Ounce per Quart and Kilogram 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
kilograms per milliliter = ounces per quart × 0.0000299566068292
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 kilogram per milliliter equals 1000000 base units, so dividing one by the other gives the direct ounce per quart-to-kilogram per milliliter factor of 0.0000299566068292.
Simple example
1 oz/qt × 0.00002995660683 = 0.0000299566 kg/mL
1 ounce per quart = 0.0000299566 kilograms per milliliter.
Real-world example
1,000 oz/qt × 0.00002995660683 = 0.0299566068 kg/mL
1,000 ounces per quart = 0.0299566068 kilograms per milliliter.

Frequently asked questions
How many kilograms per milliliter are in 1 ounce per quart?
1 ounce per quart equals 0.0000299566 kilograms per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per quart to kilogram per milliliter?
Multiply the ounce per quart value by 0.00002995660683. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per milliliter back to ounce per quart?
Use the reverse factor: 1 kilogram per milliliter equals 33,381.61781 ounces per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per quart?
Ounce per Quart (oz/qt) is a unit of density.
What is a kilogram per milliliter?
Kilogram per Milliliter (kg/mL) is a unit of density.
Is the ounce per quart to kilogram per milliliter conversion exact?
Yes. Both ounce per quart and kilogram per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.00002995660683 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.
