# Calculate Carnot Efficiency

Calculator for the Carnot efficiency from the temperature ratio of the process. The Carnot efficiency or Carnot factor describes the maximum amount of energy that can be used when converting heat into motion. This depends on the lowest temperature (cold, T_{k}) and the highest temperature (hot, T_{h}) in the process. This process can be combustion, as in the internal combustion engine. The fuel in the cylinder is at its lowest temperature when it is at its largest volume and at its highest temperature at its smallest volume when it is most compressed.

The Carnot efficiency η_{c} is calculated with the formula _{c} = ( 1 - T_{k}/T_{h} ) * 100%

The temperature can be specified in degrees Celsius, Fahrenheit or in Kelvin, calculations are made in Kelvin. Please enter one cold and one hot temperature.
