Enter the mass of the explosive material and the energy per unit mass into the calculator to determine the explosion yield. The yield is the total energy released by the explosion.

Explosion Yield Formula

The following formula is used to calculate the explosion yield.

Y = M * E


  • Y is the explosion yield (megajoules)
  • M is the mass of the explosive material (kilograms)
  • E is the energy per unit mass (megajoules per kilogram)

To calculate the explosion yield, multiply the mass of the explosive material by the energy per unit mass.

What is Explosion Yield?

Explosion yield is a measure of the energy released when an explosive material detonates. It is typically expressed in terms of megajoules or equivalent tons of TNT. The yield is an important factor in assessing the potential damage and impact of an explosion, and it is used in various fields such as mining, demolition, and military applications.

How to Calculate Explosion Yield?

The following steps outline how to calculate the Explosion Yield.

  1. First, determine the mass of the explosive material (M) in kilograms.
  2. Next, determine the energy per unit mass (E) in megajoules per kilogram.
  3. Next, gather the formula from above = Y = M * E.
  4. Finally, calculate the Explosion Yield (Y) in megajoules.
  5. 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.

Mass of the explosive material (M) = 50 kilograms

Energy per unit mass (E) = 4.184 megajoules per kilogram (equivalent to 1 kilogram of TNT)
