About Converting Carats per Gallon to Long tons per Milliliter
Carat per Gallon and Long ton per Milliliter 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 milliliter = carats per gallon × 5.199997e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per gallon equals 0.0528344104716 base units, and 1 long ton per milliliter equals 1016046908.8 base units, so dividing one by the other gives the direct carat per gallon-to-long ton per milliliter factor of 5.199997e-11.
Simple example
1 ct/gal × 5.199997e-11 = 5.199997e-11 long ton/mL
1 carat per gallon = 5.199997e-11 long tons per milliliter.
Real-world example
1,000 ct/gal × 5.199997e-11 = 5.199997e-8 long ton/mL
1,000 carats per gallon = 5.199997e-8 long tons per milliliter.

Frequently asked questions
How many long tons per milliliter are in 1 carat per gallon?
1 carat per gallon equals 5.199997e-11 long tons per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per gallon to long ton per milliliter?
Multiply the carat per gallon value by 5.199997e-11. The converter above does this instantly to whatever precision you set.
How do I convert long ton per milliliter back to carat per gallon?

What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
What is a long ton per milliliter?
Long ton per Milliliter (long ton/mL) is a unit of density.
Is the carat per gallon to long ton per milliliter conversion exact?
Yes. Both carat per gallon and long ton per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 5.199997e-11 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.
