How to calculate efficiency
The most straightforward method for calculating efficiency involves dividing the output value by the input value and multiplying by 100. The formula is as follows: Efficiency (%) = (Output / Input) x 100. For example, if an engine produces 400 units of work using 500 units of fuel, its efficiency would be (400/500) x 100 = 80%.
