135milliwatts =. 135watts.

Now for coverting watts to kilowatts we have to divide by 1000.

So turn to be 135*10^-6 or = 1. 35*10^-4.

1mW=10^-3W
135mW=135*10^-3W
Again, 1KW=10^3W or, 1W=0.001KW

So, 135*10^-3W = 0.001*135*10^-3W
= 135*10^-3*10^-3W
=135*10^-6W
=1.35*10^-4W

Dear Prashant you are wrong, because.

1 Milliwatt = 1/1000 watt.

135 Milliwatt = 0. 135 watt.

1 Watt = 1/1000 KW.

0. 135 watt = 0. 135 x (1/1000) = 0. 000135 =1. 35 × 10^–4 kW.

135miliwatt=135/1000watts.
1watt=1/1000kwatt.

Therefore;

135miliwatt=135/1000000.
So Answer (a) is correct.

135milliwatts=135*10^-3=.135watts and 1kw=1000watts.

So 1watt=1/1000=0.001 kw.

So 135milliwatts=.135*0.001=1.35*10^-4kw.

135 mW = 13.5 W
Now 1 kW = 1000 W
So 1 W = 0.001 kW

Hence 135 mW = 13.5 * 0.001 kw
=> 13.5 * 10^-3 kW
=> 1.35 * 10^ -4
=> Answer: A.

We know,

135mW = 135/1000w = .135w = . 35/1000 kw.

Which is equal to option (A).

1.35 *10^-4 kW.

1.35 *10^-4 *10^3W.

1.35 *10^-1W.

So 135 mW.

135*10^-3w.
To convert to KW.
Divide and multiply by 10^3 to reduce the unit to W.

Again to reduce the unit to KW divide by 10^3.

1mW = 0.001W.
1W = 0.001KW.
Therefore, 1mW = .000001 kW.

Hence 135mW = 135*.000001 kW.
=1.35*10^-4 kW answer.
