About Converting Decagrams per Pint to Long tons per Gallon
Decagram per Pint and Long ton per Gallon 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 gallon = decagrams per pint × 0.0000787365222089
This factor comes from each unit's defined relationship to the category's base unit: 1 decagram per pint equals 21.1337641887 base units, and 1 long ton per gallon equals 268411.19719 base units, so dividing one by the other gives the direct decagram per pint-to-long ton per gallon factor of 0.0000787365222089.
Simple example
1 dag/pt × 0.00007873652221 = 0.0000787365 long ton/gal
1 decagram per pint = 0.0000787365 long tons per gallon.
Real-world example
1,000 dag/pt × 0.00007873652221 = 0.0787365222 long ton/gal
1,000 decagrams per pint = 0.0787365222 long tons per gallon.

Multiply the decagram per pint value by 0.00007873652221. The converter above does this instantly to whatever precision you set.
How do I convert long ton per gallon back to decagram per pint?
Use the reverse factor: 1 long ton per gallon equals 12,700.58636 decagrams per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a decagram per pint?
Decagram per Pint (dag/pt) is a unit of density.
What is a long ton per gallon?
Long ton per Gallon (long ton/gal) is a unit of density.
Is the decagram per pint to long ton per gallon conversion exact?
Yes. Both decagram per pint and long ton per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.00007873652221 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.
