About Converting Long tons per Cubic Meter to Pounds per Cup
Long ton per Cubic Meter and Pound per Cup 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 cup = long tons per cubic meter × 0.52995764976
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cubic meter equals 1016.0469088 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct long ton per cubic meter-to-pound per cup factor of 0.52995764976.
Simple example
1 long ton/m3 × 0.5299576498 = 0.5299576498 lb/cup
1 long ton per cubic meter = 0.5299576498 pounds per cup.
Real-world example
1,000 long ton/m3 × 0.5299576498 = 529.9576498 lb/cup
1,000 long tons per cubic meter = 529.9576498 pounds per cup.

How do I convert pound per cup back to long ton per cubic meter?
Use the reverse factor: 1 pound per cup equals 1.886943231 long tons per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per cubic meter?
Long ton per Cubic Meter (long ton/m3) is a unit of density.
What is a pound per cup?
Pound per Cup (lb/cup) is a unit of density.
Is the long ton per cubic meter to pound per cup conversion exact?
Yes. Both long ton per cubic meter and pound per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.5299576498 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.
