1watt = 10^3millwatts.
1millwatts = 1\10^3watt,
= 10^-3watts.

1Kw = 10^3watts,
1watt = 1/10^3kilowatts,
= 10^-3kilowatts.

135milliwatts = 135 * 10^-3watt,
= 135*(10^-3)*(10^-3) kilowatts,
= (135/10^2)*10^(-3-1) kilowatts,
= 1.35*10^-4kilowatts.

135milli watt = 135 * 10^-3 watt,
1 watt = 0.001 kw
So 135 * 10^-3 watt.
= 0.001 * 135 * 10^-3 = 0.000135 Kw = 1.35 * 10^-4 kw.

Given: 135milliwatt.

=> 135x10^-3 : To convert it into kilowatts, lets multiply and divide it by 10^3.

=> 135x10^-3 x 1/10^3 KW.

=> 135x10^-6 KW (cause when denominator goes to numerator, '+' becomes "-" so).

=> 135x10^-6 KW => 13.5x10^-5 KW => 1.35x10^-4 KW.

Hence the answer is 1.35x10^-4 KW.

135 milliwatts = 135 x 10^-3 watt = 135 x 10^-6,

135 x 10^-6 = 13.5 x 10^-5 = 1.35 x 10^-4 is the answer.

We know 1 milliwatt = 10^-3.
So, 135 milliwatts = 135 * 10^-3 = 0.135 w.

We also know 1kw = 1000 w.
So the result is (0.135/1000) = 1.35 * 10^-4.

135 milliwatts = 13.5 watts.
Now 1 kilowatt = 1000 watts.

So 1 watt = 0. 001 kilowatts.
Hence 135 milliwatts = 13.5 * 0.001 kilowatts.
= 13.5 * 10^-3 kW.
= 1.35 * 10^ -4.

The most important term here is 1mW = 1000W.

135 mw = 0.135 w.

= 0.135E-3 KW.

(135/10E 3)*(E - 3).

= 135*E-6 KW.

= 13.5*E-5 KW.

= 1.35*E-4 KW.
