About Converting Metric tons per Gallon to Long tons per Cup
Metric ton per 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 = metric tons per gallon × 0.0615129079757
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per gallon equals 264172.052358 base units, and 1 long ton per cup equals 4294579.15504 base units, so dividing one by the other gives the direct metric ton per gallon-to-long ton per cup factor of 0.0615129079757.
Simple example
1 t/gal × 0.06151290798 = 0.061512908 long ton/cup
1 metric ton per gallon = 0.061512908 long tons per cup.
Real-world example
1,000 t/gal × 0.06151290798 = 61.51290798 long ton/cup
1,000 metric tons per gallon = 61.51290798 long tons per cup.

What is a metric ton per gallon?
Metric ton per Gallon (t/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 metric ton per gallon to long ton per cup conversion exact?
Yes. Both metric ton per gallon and long ton per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.06151290798 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.
