Frequently Asked Questions
What is power in physics?
Power is the rate at which work is done or energy is transferred per unit of time. It quantifies how quickly energy is used or generated.
Why are there different power units?
Different power units (like Watts, horsepower, BTU/h) evolved for various applications (electrical, mechanical, thermal) and historical or regional preferences.
What is the SI unit for power?
The SI (International System of Units) unit for power is the Watt (W). One Watt is defined as one joule per second.
How does power relate to energy?
Power is the rate of energy transfer or consumption. Energy is the total amount of work done or heat exchanged, while power describes how fast this happens.
What are common uses of power units like HP and Watts?
Horsepower (HP) often measures engine output (cars, motors). Watts (W) typically measure electrical power (light bulbs, appliances) or general power in physics.
Can I convert between all power units?
Yes, most power units can be converted to others because they all measure the same physical quantity – the rate of energy transfer. Converters use established mathematical factors.
