About Converting Metric tons per Gallon to Pounds per Cup
Metric ton per Gallon and Pound 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
pounds per cup = metric tons per gallon × 137.788913866
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 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct metric ton per gallon-to-pound per cup factor of 137.788913866.
Simple example
1 t/gal × 137.7889139 = 137.7889139 lb/cup
1 metric ton per gallon = 137.7889139 pounds per cup.
