What is efficiency formula physics? Efficiency = useful power out total power in. It can be written as a number between 0 and 1 or as a %. For example, an efficiency of 0.25 is the same as an efficiency of 25%. Because some energy is always wasted from every device, efficiency should always be less than 1 or less than 100%.
