The free Energy Efficiency Calculator tool is designed to quickly determine energy proportions. To examine the energy efficiency as an output, simply insert input and output energy into the calculator's input boxes and press the calculate button.
What is Energy Efficiency and its Formula?
Efficiency is defined as the degree to which the output matches the input with the least amount of waste feasible. The ratio of output energy created to input energy used is known as energy efficiency. It is denoted by the symbol, η. Return on investment and fuel economy are of real-time applications.
The following is the energy efficiency formula: η = (Energy output/Energy input)*100%
How do you find the Efficiency?
The steps to determine the energy efficiency of appliances are outlined below. To get the outcome in a shorter length of time, follow these concepts and rules.
- Determine the input and output energy.
- Divide the input energy from the produced energy.
- To get the efficiency value, multiply the resulting value by 100.

Question 1:A heat engine uses 1620 J of energy as input and outputs 350 J of useful heat energy. How do you figure out how efficient heat energy is?
Consider the problem, we have
Energy output = 1620J
Energy input = 350J
Efficiency = (Energy Output)/(Energy Input)*100%
Efficiency = 1620/350 * 100%
Efficiency = 5.5 * 100%
Therefore, efficiency of the heat engine is 550%.
FAQs on Efficiency Calculator
1. What is the formula for calculating efficiency?
The ratio of output energy to input energy is known as efficiency. To check the result, divide the output energy by the input energy and multiply the result by 100.
2. What is the efficiency unit?
Because the numerator and denominator have the same unit, the efficiency has no unit.
3. What are the distinctions between efficiency and effectiveness?
The degree to which someone or something succeeds in achieving the desired result is referred to as effectiveness. Efficiency is defined as the ability to complete tasks with the least amount of time spent and the most efficient use of resources. It is efficient to accomplish a task correctly, and it is effective to perform a task accurately.
4. Can you give any instances of energy-saving appliances?
Ceiling fans, air purifiers, heat pumps, dishwashers, refrigerators, and other energy-efficient equipment are examples.
5. What is the energy efficiency calculation formula?
The method of estimating energy efficiency is (Output energy/input energy)*100%.
