Trying to find cost by watts
hi names gavin silly question maybe but I'm trying to find the cost of my office air conditioner I have been doing it for work experience and have to find out how much everything is costing in the office by using the sum kwh x time on a day x current kwh price and I'm using energy plugs which tell me exactly how much each item is using but the air conditioner doesn't plug in
phase ~/n
volts 220/230
hz 60/50
ip code ip 20
input (in) 0.07 kw
these are the details on the unit I have been using the above input amount of watts but my amount just seems to cheap to be right help would be appreciated thanks
