Coal is one of the most widely used sources of energy for power generation and industrial applications. To estimate the energy produced from burning a specific amount of coal, you need to know its energy content per kilogram. The Coal Energy Conversion Calculator helps determine the total energy output based on the mass of coal and its energy content.
Formula
The total energy output from coal combustion is calculated using:
E = m × e_c
Where:
- E = Total energy output (in megajoules, MJ)
- m = Mass of coal used (in kilograms, kg)
- e_c = Energy content of coal (in megajoules per kilogram, MJ/kg)
How to Use
Using the Coal Energy Conversion Calculator is simple:
- Enter the mass of coal in kilograms.
- Input the energy content per kg of coal in MJ/kg.
- Click the Calculate button.
- The calculator will display the total energy output in MJ.
Example
Suppose:
- The mass of coal used (m) is 10 kg.
- The energy content per kg (e_c) is 25 MJ/kg.
Applying the formula:
E = 10 × 25 = 250 MJ
So, the total energy output from burning 10 kg of coal is 250 megajoules.
