About Converting Megagrams per Cup to Long tons per Oil barrel
Megagram per Cup and Long ton per Oil barrel 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 oil barrel = megagrams per cup × 661.386786555
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per cup equals 4226752.83773 base units, and 1 long ton per oil barrel equals 6390.74279023 base units, so dividing one by the other gives the direct megagram per cup-to-long ton per oil barrel factor of 661.386786555.
Simple example
1 Mg/cup × 661.3867866 = 661.3867866 long ton/bbl
1 megagram per cup = 661.3867866 long tons per oil barrel.
Real-world example

What is a megagram per cup?
Megagram per Cup (Mg/cup) is a unit of density.
What is a long ton per oil barrel?
Long ton per Oil barrel (long ton/bbl) is a unit of density.
Is the megagram per cup to long ton per oil barrel conversion exact?
Yes. Both megagram per cup and long ton per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 661.3867866 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.
