WebNational Center for Biotechnology Information WebMeasuring Heat Input Heat input can be measured three ways. First is the classic heat input formula: Heat input = Volts X Amps X 60 Travel speed In this formula, heat input is measured in Joules/inch (J/in) or Joules/mm (J/mm) depending on whether the travel speed is measured in inches per minute or millimeters per minute.
