About Converting Metric tons per Cubic Meter to Long tons per Oil barrel
Metric ton per Cubic Meter 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 = metric tons per cubic meter × 0.156476333475
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per cubic meter equals 1000 base units, and 1 long ton per oil barrel equals 6390.74279023 base units, so dividing one by the other gives the direct metric ton per cubic meter-to-long ton per oil barrel factor of 0.156476333475.
Simple example
1 t/m3 × 0.1564763335 = 0.1564763335 long ton/bbl
1 metric ton per cubic meter = 0.1564763335 long tons per oil barrel.
Real-world example
1,000 t/m3 × 0.1564763335 = 156.4763335 long ton/bbl
1,000 metric tons per cubic meter = 156.4763335 long tons per oil barrel.

Frequently asked questions
How many long tons per oil barrel are in 1 metric ton per cubic meter?
1 metric ton per cubic meter equals 0.1564763335 long tons per oil barrel, using the exact defined conversion factor rather than an estimate.
How do I convert metric ton per cubic meter to long ton per oil barrel?
Multiply the metric ton per cubic meter value by 0.1564763335. The converter above does this instantly to whatever precision you set.
How do I convert long ton per oil barrel back to metric ton per cubic meter?
Use the reverse factor: 1 long ton per oil barrel equals 6.39074279 metric tons per cubic meter. You can also use the swap control in the converter above to flip the direction instantly.
What is a metric ton per cubic meter?
Metric ton per Cubic Meter (t/m3) 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 metric ton per cubic meter to long ton per oil barrel conversion exact?
Yes. Both metric ton per cubic meter and long ton per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.1564763335 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.
