About Units

Watt: The watt (W) is a unit of power in the International System of Units (SI), equivalent to one joule per second. It is named after James Watt, an 18th-century Scottish inventor. Watts are commonly used to measure the rate of energy transfer in electrical systems. For example, a typical incandescent light bulb consumes about 60 watts of power.

Kilocalories per hour: Kilocalories per hour (kcal/h) is a unit of power commonly used to measure heating or cooling capacities. One kilocalorie per hour is the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius in one hour. It is often used in heating and cooling applications.
