Physical Power Calculator

Calculate the power from work and time, with different units. In physics, power is work per time, P=W/t. So power is, what is done by enduring work. The unit of power is the watt, W. This W for the unit watt must not be confused with the previous W for the dimension work. Watt = joule per second, 1W=1J/s.

Work W: millijoules, mJjoules, J, Nm, Wskilojoules, kJmegajoules, MJwatt-hours, Whkilowatt-hours, kWh

	days	hours	minutes	seconds
Time t:

Power P: milliwatts, mWwatts, Wkilowatts, kWmegawatts, MWgigawatts, GW

Example: 5 megajoules of work should be achived within two hours. Therefore, a constant power of almost 0.7 kilowatts is needed.
