Commercial Unit of Energy
Commercial Unit of Energy : - The SI unit of energy is the joule (J). But the commonly used unit for electrical - energy consumption is the kilowatt-hour (kWh). If energy is consumed at the rate of 1 Kilo Joule / second, i.e., at the rate of 1 Kilo Watt, and this continues for 1 hour then the total energy consumed is called 1 KiloWatt - Hour.
Thus,
For electrical - energy consumption in houses, factories, shops, etc, kilowatt - hour is simply called ' unit'. So, the cost of electrical energy is given in terms of Rs/unit.
