About Converting Centigrams per Imperial gallon to Long tons per Cup
Centigram per Imperial gallon and Long ton 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
long tons per cup = centigrams per imperial gallon × 5.122021e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 centigram per imperial gallon equals 0.00219969248299 base units, and 1 long ton per cup equals 4294579.15504 base units, so dividing one by the other gives the direct centigram per imperial gallon-to-long ton per cup factor of 5.122021e-10.
Simple example
1 cg/imp gal × 5.122021e-10 = 5.122021e-10 long ton/cup
1 centigram per imperial gallon = 5.122021e-10 long tons per cup.
Real-world example
1,000 cg/imp gal × 5.122021e-10 = 5.122021e-7 long ton/cup
1,000 centigrams per imperial gallon = 5.122021e-7 long tons per cup.

Multiply the centigram per imperial gallon value by 5.122021e-10. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cup back to centigram per imperial gallon?
Use the reverse factor: 1 long ton per cup equals 1,952,354,335 centigrams per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a centigram per imperial gallon?
Centigram per Imperial gallon (cg/imp gal) is a unit of density.
What is a long ton per cup?
Long ton per Cup (long ton/cup) is a unit of density.
Is the centigram per imperial gallon to long ton per cup conversion exact?
Yes. Both centigram per imperial gallon and long ton per cup are defined by fixed standards rather than physical artifacts, so the factor of 5.122021e-10 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.
