Fire Load Formula

The following equation is used to calculate the Fire Load.

FL = (M*C)/A
  • Where FL is the fire load (kJ/m^2)
  • M is the mass of the material (kg)
  • C is the calories in the material (kJ/kg)
  • A is the total area (m^2)

To calculate the fire load, multiply the mass of the materials in the building by the calories in the material, then divide by the total area.
