About Converting Long tons per Cup to Megagrams per Gallon
Long ton per Cup and Megagram 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
megagrams per gallon = long tons per cup × 16.2567505408
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 megagram per gallon equals 264172.052358 base units, so dividing one by the other gives the direct long ton per cup-to-megagram per gallon factor of 16.2567505408.
Simple example
1 long ton/cup × 16.25675054 = 16.25675054 Mg/gal
1 long ton per cup = 16.25675054 megagrams per gallon.
Real-world example
1,000 long ton/cup × 16.25675054 = 16,256.75054 Mg/gal
1,000 long tons per cup = 16,256.75054 megagrams per gallon.

Frequently asked questions
How many megagrams per gallon are in 1 long ton per cup?
1 long ton per cup equals 16.25675054 megagrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert long ton per cup to megagram per gallon?
Multiply the long ton per cup value by 16.25675054. The converter above does this instantly to whatever precision you set.
How do I convert megagram per gallon back to long ton per cup?
Use the reverse factor: 1 megagram per gallon equals 0.061512908 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 megagram per gallon?
Megagram per Gallon (Mg/gal) is a unit of density.
Is the long ton per cup to megagram per gallon conversion exact?
Yes. Both long ton per cup and megagram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 16.25675054 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.
