A kilowatt (kW) is a standard unit used to measure power.
It's part of the metric system and is equal to exactly one thousand watts (1,000 W).
The prefix "kilo-" simply means one thousand, which makes converting between watts and kilowatts easy:
1 kilowatt (kW) = 1,000 watts (W)
You'll commonly see this unit on labels for engines, electric motors, and many household appliances to indicate their power consumption or output.
It's easy to mix these two up, but the distinction is crucial: they measure power versus energy.
When you get your electricity bill, you are being charged for the total energy you used (the kilowatt-hours).
You are not charged for the peak power you demanded (the kilowatts).
You can find kilowatt (kW) power ratings on many high-power devices in your home.
This rating indicates how much power a device requires to operate. Here are a few typical examples:
To summarize, just remember these key points:
A watt (W) is the basic unit of power used to measure the rate of energy transfer.
In simple terms, it tells you how much energy a device uses per second. For example, a 60-watt light bulb uses 60 joules of energy every second.
In electrical systems, the formula is Watts = Volts × Amps.
The unit of power, the watt (W), is named in honor of James Watt, an 18th-century Scottish inventor and engineer.
His groundbreaking improvements to the steam engine were a key part of the Industrial Revolution. Naming the unit after him honors his major contributions to energy science.
Formally, a watt is defined as the rate of energy transfer equal to one joule per second.
In electrical systems, one watt is the power produced when a current of one ampere (A) flows through an electrical potential difference of one volt (V).
This fundamental relationship is a cornerstone of electrical engineering.
The relationship between power (P), voltage (V), and current (I) is expressed by the simple formula:
P = V × I
Where:
Understanding watts helps you see how much energy your common devices consume.
This is essential for comparing the energy efficiency of appliances and understanding your electricity bill. Here are some practical examples:
By checking the wattage on your devices, you can get a better sense of which ones use the most power in your home.
