How many kilo-calories of heat does the operation of a 1200-w hair dryer produce each second?

The answer in SI units is 1200 joules or 1.2 kilojoules. the definition of a joule is one watt second. in Calories, or English units, which shouldn't really be used with watts as it mixes systems of measurements, is 286.806883 calories or 0.286806883 kilo calories.

Who the heck would know that?

You've got me stumped! I didn't know you could produce kilo-calories from an electrical appliance. I was thinking kilo-watts.



But you're excused since this is your first question.



How many kilo-calories of heat does the operation of a 1200-w hair dryer produce each second?

kilo-watts is a measure of electricity and its measured in hours.And heat produced by it would be measured in btu's(British Thermal Units).Kilo-calories has nothing to do with it.
