  • Efficiency Calculator

    Efficiency is defined as the ratio of energy output to energy input. Every time that you supply energy or heat to a machine (for example to a car engine) a certain part of this energy is wasted and only some is converted to actual work output. The more efficient the machine the higher output it produces.
