1 candle power equals how many horse power?

The combustion of an average candle produces about 80 watts of energy.
37 kilojoules (kJ) per gram.
Consuming about 2 thousandths of a gram each second, producing more heat energy than light.
From there the conversion is: 80 watts = ~0.107282 mechanical hp

This is what quarantine bored looks like...
