What is the unit of measurement for power?

Power is defined as the rate at which work is done or energy is transferred over time. The standard unit of measurement for power in the International System of Units (SI) is the watt (W). One watt is equivalent to one joule per second, which signifies that one watt of power is produced when one joule of energy is transferred in one second.

The other units listed serve different functions: joules measure energy or work, newtons measure force, and pascals measure pressure. Each of these is essential in its context but does not represent power, making watts the correct and relevant unit for this specific concept.
