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.)

What is the relationship of work Energy and power?
Work is the transfer of mechanical energy; its units are the same as for energy, for example joule. Power is the rate of transfer of energy, and it has units of energy/time, for example watt.
How does railway refrigeration works?
The refrigeration units take their power from the locomotive.
How much does 95 to the third power weigh?
857,375 units of weight.
What are the units for energy and power?
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.)
How do you label possible units for power and energy in physics?
Joules per second or watts
What is the units digit of 7 to the 15 power?
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.
How do you express 795000 units of power generated in megawatt?
It is not clear what you mean with "units of power".
Watts and horsepower are both units of what?

How is plutonium used in spacecrafts?
As radio-isotopic power units or heating units.
What are the units for solar power?
watts
Power supply units are rated in?
Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
The maximum power output of an engine is usually given in units called?
It's given in the units called: BHP=Brake Horse Power
In what units to you express apparent power?
VA
What is the speed at which energy is transfered?

Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts
What is power's formula?
In very general terms, power is work (or energy, same units) per unit time. In SI units, power is measured in watts, which are joules per second.
