Enter the supercapacitor energy density (Wh/kg) and the supercapacitor mass (kg) into the calculator to determine the Supercapacitor Energy. 

Supercapacitor Energy Formula

The following equation is used to calculate the Supercapacitor Energy. 

ES = ED * m * 3600


  • Where ES is the Supercapacitor Energy (Joules)
  • ED is the supercapacitor energy density (Wh/kg) 
  • m is the supercapacitor mass (kg) 

How to Calculate Supercapacitor Energy?

The following two example problems outline the steps and information needed in order to calculate the Supercapacitor Energy.

Example Problem #1:

  1. First, determine the supercapacitor energy density (Wh/kg). In this example, the supercapacitor energy density (Wh/kg) is measured to be 5.
  2. Next, determine the supercapacitor mass (kg). For this problem, the supercapacitor mass (kg) is calculated to be 4.
  3. Finally, calculate the Supercapacitor Energy using the formula above: 

ES = ED * m * 3600

Inserting the values from above and solving the equation with the imputed values gives: 

ES = 5 * 20 * 3600 = 360,000 (Joules)

Example Problem #2: 

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as: 

supercapacitor energy density (Wh/kg) = 6

supercapacitor mass (kg) = 4

Entering these values into the formula or calculator above gives us: 

ES = 6 * 4 * 3600 = 432,000 (Joules)
