About Converting Ounces per Cubic Millimeter to Long tons per Quart
Ounce per Cubic Millimeter and Long ton per Quart 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
long tons per quart = ounces per cubic millimeter × 26.4049371094
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic millimeter equals 28349523.125 base units, and 1 long ton per quart equals 1073644.78876 base units, so dividing one by the other gives the direct ounce per cubic millimeter-to-long ton per quart factor of 26.4049371094.
Simple example
1 oz/mm3 × 26.40493711 = 26.40493711 long ton/qt
1 ounce per cubic millimeter = 26.40493711 long tons per quart.
Real-world example
1,000 oz/mm3 × 26.40493711 = 26,404.93711 long ton/qt
1,000 ounces per cubic millimeter = 26,404.93711 long tons per quart.

How do I convert long ton per quart back to ounce per cubic millimeter?
Use the reverse factor: 1 long ton per quart equals 0.0378717054 ounces per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per cubic millimeter?
Ounce per Cubic Millimeter (oz/mm3) is a unit of density.
What is a long ton per quart?
Long ton per Quart (long ton/qt) is a unit of density.
Is the ounce per cubic millimeter to long ton per quart conversion exact?
Yes. Both ounce per cubic millimeter and long ton per quart are defined by fixed standards rather than physical artifacts, so the factor of 26.40493711 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.
