Calculation Formula

Energy per unit mass (specific energy) = Total Energy / Mass

Where:
- Energy per unit mass (specific energy) is measured in Joules per kilogram (J/kg)
- Total Energy is measured in Joules (J)
- Mass is measured in kilograms (kg)

Working Principle

Specific energy (or energy per unit mass) is a measure of the energy contained per unit of mass. It is calculated by dividing the total energy by the mass of the system. This value is particularly important in fields such as thermodynamics, where it helps in understanding the energy density of fuels, batteries, and other energy storage systems.

Example Calculation

Suppose you have a fuel that provides 10,000 Joules of energy and has a mass of 2 kilograms. The specific energy would be calculated as follows:

Specific Energy = 10,000 J / 2 kg = 5,000 J/kg

Applications

This calculator is useful in various applications including:

  • Energy storage systems (batteries, fuel cells)
  • Fuel efficiency analysis
  • Thermal energy systems
  • Material science for energy density measurements
