## Watt and Kilowatt hour

Watt and kilowatt hour are both units of measurement used in the world of electricity and energy.

### What is Watt?

Watt, named after the Scottish engineer James Watt, is a unit of power in the International System of Units (SI). It represents the rate of energy transfer or conversion. If a device has a power of 1 watt, it means that it consumes 1 joule of energy per second. Power is often used to indicate the capacity of devices such as lamps and heating systems.

For example, a 100 watt lamp consumes 100 joules of energy per second. The higher the number of watts, the more energy the device consumes per second.

### What is Kilowatt hour?

Kilowatt hour, on the other hand, is a unit of energy. It is the amount of energy consumed when a device that consumes 1 kilowatt (or 1000 watts) is used for one hour. This unit is often used on electricity bills, as it is a way to measure energy consumption over a certain period. One kilowatt hour is equivalent to 3.6 million joules.

For example, if a 100 watt lamp burns for 10 hours, then it consumes 1 kilowatt hour (kWh) of energy (100 watts * 10 hours = 1000 watt hours = 1 kWh).

In short, watt measures the rate of energy consumption, while kilowatt hour measures the total amount of energy consumed over a certain period.
