About Converting Pounds per Cubic Centimeter to Long tons per Cubic Meter
Pound per Cubic Centimeter and Long ton per Cubic Meter 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 meter = pounds per cubic centimeter × 446.428571429
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic centimeter equals 453592.37 base units, and 1 long ton per cubic meter equals 1016.0469088 base units, so dividing one by the other gives the direct pound per cubic centimeter-to-long ton per cubic meter factor of 446.428571429.
Simple example
1 lb/cm3 × 446.4285714 = 446.4285714 long ton/m3
1 pound per cubic centimeter = 446.4285714 long tons per cubic meter.
Real-world example
1,000 lb/cm3 × 446.4285714 = 446,428.5714 long ton/m3
1,000 pounds per cubic centimeter = 446,428.5714 long tons per cubic meter.

Frequently asked questions
How many long tons per cubic meter are in 1 pound per cubic centimeter?
1 pound per cubic centimeter equals 446.4285714 long tons per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cubic centimeter to long ton per cubic meter?
Multiply the pound per cubic centimeter value by 446.4285714. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cubic meter back to pound per cubic centimeter?
Use the reverse factor: 1 long ton per cubic meter equals 0.00224 pounds per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cubic centimeter?
Pound per Cubic Centimeter (lb/cm3) is a unit of density.
What is a long ton per cubic meter?
Long ton per Cubic Meter (long ton/m3) is a unit of density.
Is the pound per cubic centimeter to long ton per cubic meter conversion exact?
Yes. Both pound per cubic centimeter and long ton per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 446.4285714 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.
