The unit ‘watt’ is relatively small for practical usage, so a larger unit called ‘kilowatt’ is commonly employed. One kilowatt is equivalent to 1000 watts, making it more convenient to express power values in practical scenarios.
Why is the unit ‘kilowatt’ commonly used in practical applications, and how does it relate to the standard unit ‘watt’?

The unit ‘kilowatt’ is commonly used in practical applications because it represents a larger and more practical measure of electrical power. One kilowatt (kW) is equivalent to 1000 watts. Since many electrical devices, especially in domestic and industrial settings, have power ratings in the thousands of watts, the kilowatt provides a more manageable and convenient scale. It simplifies billing, discussions about power consumption, and the specification of equipment capacity. The kilowatt is derived from the standard unit ‘watt,’ where 1 kilowatt equals 1000 watts, making it easier to express and comprehend power values in real-world scenarios.
