The best unit to use for power are the SI one, the ' Watt'.
1 watt = 1 joule of energy per second.
Even in the vast number of countries where they still don't use the metric system ...
Liberia, Myanmar, and the USA ... most people use ' Watts ' for power anyway.
But you might also occasionally hear "foot-pounds per second" and "horsepower"
in some places.
1 horsepower = 550 foot-pounds per second.
1 horsepower = 746 watts.
(This second conversion factor is easy to remember: The mainsails on the
Nina, the Pinta, and the Santa Maria were estimated to have developed
about 2 horsepower in a fresh breeze. They sailed in 1492. 1492/2 = 746.)
The units for work are joules (J) in the International System of Units (SI). The units for power are watts (W), which is equivalent to one joule per second (J/s).
The SI units are as follows: The unit for energy is the Joule. The unit for power is the Watt, which is equal to Joules/second. (Therefore, you might also say that a Joule is a Watt times a second.)
Yes, a quantity can have units but still be dimensionless if the units cancel out when they are raised to the power of 0. For example, specific volume (volume per mass) has units of m^3/kg, but when you divide volume by mass, the units cancel out and it becomes dimensionless.
Power and work both have the same SI units, which are joules per second (J/s), also known as watts (W).
The different optical power units used to measure the intensity of light in optical systems are diopters and watts. Diopters measure the refractive power of a lens, while watts measure the total power of light emitted or transmitted through a system.
Power 2: units digit 9. Multiply by 49 again to get power 4: units digit 1. So every 4th power gives units digit 1. So 16th power has units digit 1, so the previous power, the 15th must have units digit 3.
Watts and horsepower are both units of power.
It is not clear what you mean with "units of power".
squared as in square units and to the third power it would be cubed as in cubed units

Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
It's given in the units called: BHP=Brake Horse Power
VA
