About Converting Long tons per Cup to Imperial hundredweights per Gallon
Long ton per Cup and Imperial hundredweight 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
imperial hundredweights per gallon = long tons per cup × 320
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cup equals 4294579.15504 base units, and 1 imperial hundredweight per gallon equals 13420.5598595 base units, so dividing one by the other gives the direct long ton per cup-to-imperial hundredweight per gallon factor of 320.
Simple example
1 long ton/cup × 320 = 320 long cwt/gal
1 long ton per cup = 320 imperial hundredweights per gallon.
Real-world example
1,000 long ton/cup × 320 = 320,000 long cwt/gal
1,000 long tons per cup = 320,000 imperial hundredweights per gallon.

Multiply the long ton per cup value by 320. The converter above does this instantly to whatever precision you set.
How do I convert imperial hundredweight per gallon back to long ton per cup?
Use the reverse factor: 1 imperial hundredweight per gallon equals 0.003125 long tons per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per cup?
Long ton per Cup (long ton/cup) is a unit of density.
What is a imperial hundredweight per gallon?
Imperial hundredweight per Gallon (long cwt/gal) is a unit of density.
Is the long ton per cup to imperial hundredweight per gallon conversion exact?
Yes. Both long ton per cup and imperial hundredweight per gallon are defined by fixed standards rather than physical artifacts, so the factor of 320 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.
