1,000 w = 1.000 kw
100 w = 0.100 kw
90 w = 0.090 kw
1.2 kW is 1200 W.
You need to understand the difference between power - as in watts - and energy - as in Watt hours. Watts/kiloWatts only tells you what it's doing at the moment, at that very instant. While Wh/kWh tell you the sum of what it's been doing over a certain time. 1 kW = 1000 w So 90 W / 1000 W = 0.09 kW As soon at the light is turned on, the lamp starts to use energy at the rate of 90 W = 0.09 kW If you leave it on for 12 hours it will have used up 0.09 x 12 = 1.08 kWh
(1000 w / 1 kw) = (8645 w / N ) (1000w)N = 8645 w/kw (Apply MPE, Multiply both sides by 1/1000w) N = 8.654 kw
The formula you are looking for is I = W/E. W = kW x 1000.
There are 14 000 W in 14 kW. A watt is the unit for power, which is the rate of doing work.
1 kW = 1000 w So 500 W / 1000 W = 0.5 kW As soon at the heater is turned on, it starts to use energy at the rate of 500 W = 0.5 kW. If you leave it on for 10 hours it will have used up 0.5 x 10 = 5 kWh
The same way, as you convert Appels to Carrots ........... There is a formula: KVAr = KVA / KW or cos=KW/KVA > Yes, we are treating KW, KVA, & KVAr as the 3 sides in a 90 deg TRIANGLE ! KW= vertical katede KVAr = horizontal katede KVA = hypotenuse
1 kW = 1000 w So 40 W / 1000 W = 0.04 kW As soon at the light is turned on, the lamp starts to use energy at the rate of 40 W = 0.04 kW. If you leave it on for 100 hours it will have used up 0.04 x 100 = 4 kWh
20W-50 is equal to Sae 90 W.

V X A = W .....from.. (P=IV) W = power V x A = apparent power
You can measure the output power of the motor (mechanical power or shaft power) by a speed and torque sensor. The product of speed (angular velocity to be precise) and torque is power. Is this case the output power. The SI unit of power is W, kW is 1000 W. So the power/1000=power [kW].
