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.)
"horsepower" & watts
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.
The refrigeration units take their power from the locomotive.
857,375 units of weight.
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.)
Joules per second or watts
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.
It is not clear what you mean with "units of power".
Watts and horsepower are both 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
That is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts
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.
