Ergs per minute to milliwatts converter above calculates how many milliwatts are in 'X' ergs per minute (where 'X' is the number of ergs per minute to convert to milliwatts). In order to convert a value from ergs per minute to milliwatts (from erg/min to mW) just type the number of erg/min to be converted to mW and then click on the 'convert' button.
