Enter the density of the substance and the volume in barrels into the calculator to convert the volume to metric tons. This calculator assumes that the volume is measured in oil barrels.

Barrels To Metric Tons Formula

The following formula is used to convert barrels to metric tons:

MT = D * (V * 0.1589873) / 1000


  • MT is the mass in metric tons
  • D is the density of the substance (kg/m³)
  • V is the volume in barrels

To convert barrels to metric tons, multiply the density of the substance by the volume in barrels converted to cubic meters (using the factor 0.1589873), and then divide by 1000 to convert from kilograms to metric tons.

What is a Barrel?

A barrel is a unit of volume commonly used in the oil industry to measure crude oil and other petroleum products. One barrel is equivalent to 42 US gallons or approximately 159 liters. In this context, the volume of a barrel is converted to cubic meters for the purpose of calculating mass in metric tons.

How to Calculate Metric Tons from Barrels?

The following steps outline how to calculate the mass in metric tons from the volume in barrels.

  1. First, determine the density of the substance (D) in kilograms per cubic meter (kg/m³).
  2. Next, determine the volume in barrels (V).
  3. Use the conversion factor to convert barrels to cubic meters: 1 barrel = 0.1589873 cubic meters.
  4. Apply the formula: MT = D * (V * 0.1589873) / 1000.
  5. Finally, calculate the mass in metric tons (MT).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Density of the substance (D) = 800 kg/m³

Volume in barrels (V) = 100 barrels
