Power is the speed at which work happens or energy moves from one place to another.
Here are some common units we use to measure power:
Watt (W): This is the main unit for power. One watt is the same as one joule of energy used each second. So, .
Kilowatt (kW): This is equal to 1,000 watts. We often use kilowatts when talking about larger machines or appliances. So, .
Horsepower (hp): You might see this term a lot in cars. One horsepower is roughly equal to 746 watts.
British Thermal Unit per hour (BTU/h): This unit is used when discussing heating and cooling. One BTU per hour is about 0.293 watts.
Knowing these units helps us understand how well different energy systems work and how much power they use.
