About Converting Carats per Cubic Millimeter to Long tons per Cubic foot
Carat 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 = carats per cubic millimeter × 5.57392505144
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic millimeter equals 200000 base units, and 1 long ton per cubic foot equals 35881.3579577 base units, so dividing one by the other gives the direct carat per cubic millimeter-to-long ton per cubic foot factor of 5.57392505144.
Simple example
1 ct/mm3 × 5.573925051 = 5.573925051 long ton/ft3
1 carat per cubic millimeter = 5.573925051 long tons per cubic foot.
Real-world example
1,000 ct/mm3 × 5.573925051 = 5,573.925051 long ton/ft3
1,000 carats per cubic millimeter = 5,573.925051 long tons per cubic foot.

Multiply the carat per cubic millimeter value by 5.573925051. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cubic foot back to carat per cubic millimeter?
Use the reverse factor: 1 long ton per cubic foot equals 0.1794067898 carats per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic millimeter?
Carat per Cubic Millimeter (ct/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 carat per cubic millimeter to long ton per cubic foot conversion exact?
Yes. Both carat per cubic millimeter and long ton per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 5.573925051 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.
