Question: 1 unit = how many kwh?
Answer: Not that It is not Daily Rates, It's the rate of Per Unit Where 1 unit = 1 kWh (Also Called 1 =B.T.U = Board of Trade Unit). for instance, If you switched ON a 1000 watt bulb for 1 hour, It mean you consumed 1000 watts for an hour i.e. (1000 watts for 1 hour = 1kWh = 1 unit of Energy).
