About Converting Metric tons per Gallon to Long tons per Cubic Meter
Metric ton per Gallon and Long ton per Cubic Meter 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 cubic meter = metric tons per gallon × 259.999858343
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 cubic meter equals 1016.0469088 base units, so dividing one by the other gives the direct metric ton per gallon-to-long ton per cubic meter factor of 259.999858343.
Simple example
1 t/gal × 259.9998583 = 259.9998583 long ton/m3
1 metric ton per gallon = 259.9998583 long tons per cubic meter.
Real-world example
1,000 t/gal × 259.9998583 = 259,999.8583 long ton/m3
1,000 metric tons per gallon = 259,999.8583 long tons per cubic meter.

What is a metric ton per gallon?
Metric ton per Gallon (t/gal) is a unit of density.
What is a long ton per cubic meter?
Long ton per Cubic Meter (long ton/m3) is a unit of density.
Is the metric ton per gallon to long ton per cubic meter conversion exact?
Yes. Both metric ton per gallon and long ton per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 259.9998583 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.
