About Converting Ounces per Cubic Millimeter to Long tons per Cubic foot
Ounce per Cubic Millimeter and Long ton per Cubic foot 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 cubic foot = ounces per cubic millimeter × 790.090585714
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 cubic foot equals 35881.3579577 base units, so dividing one by the other gives the direct ounce per cubic millimeter-to-long ton per cubic foot factor of 790.090585714.
Simple example
1 oz/mm3 × 790.0905857 = 790.0905857 long ton/ft3
1 ounce per cubic millimeter = 790.0905857 long tons per cubic foot.
Real-world example
1,000 oz/mm3 × 790.0905857 = 790,090.5857 long ton/ft3
1,000 ounces per cubic millimeter = 790,090.5857 long tons per cubic foot.

Multiply the ounce per cubic millimeter value by 790.0905857. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cubic foot back to ounce per cubic millimeter?
Use the reverse factor: 1 long ton per cubic foot equals 0.0012656777 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 cubic foot?
Long ton per Cubic foot (long ton/ft3) is a unit of density.
Is the ounce per cubic millimeter to long ton per cubic foot conversion exact?
Yes. Both ounce per cubic millimeter and long ton per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 790.0905857 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.
