About Converting Long tons per Imperial gallon to Carats per Cubic Millimeter
Long ton per Imperial gallon and Carat per Cubic Millimeter 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
carats per cubic millimeter = long tons per imperial gallon × 1.11749537383
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per imperial gallon equals 223499.074765 base units, and 1 carat per cubic millimeter equals 200000 base units, so dividing one by the other gives the direct long ton per imperial gallon-to-carat per cubic millimeter factor of 1.11749537383.
Simple example
1 long ton/imp gal × 1.117495374 = 1.117495374 ct/mm3
1 long ton per imperial gallon = 1.117495374 carats per cubic millimeter.
Real-world example
1,000 long ton/imp gal × 1.117495374 = 1,117.495374 ct/mm3
1,000 long tons per imperial gallon = 1,117.495374 carats per cubic millimeter.

Multiply the long ton per imperial gallon value by 1.117495374. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic millimeter back to long ton per imperial gallon?
Use the reverse factor: 1 carat per cubic millimeter equals 0.8948582906 long tons per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per imperial gallon?
Long ton per Imperial gallon (long ton/imp gal) is a unit of density.
What is a carat per cubic millimeter?
Carat per Cubic Millimeter (ct/mm3) is a unit of density.
Is the long ton per imperial gallon to carat per cubic millimeter conversion exact?
Yes. Both long ton per imperial gallon and carat per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 1.117495374 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.
