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
=> Ans= A

Praveen.C.B said: (Jan 31, 2011)  
135milliwatts=.135watts
1kilowatts=1000watts
so 1 watt=.001kilowatts
so .135watts in kilowatts=.135/1000
=1.35*10^-4
so answer is A

Kuldeep said: (Apr 18, 2011)  
135 milliwatts= 135*10^-3 watts
we can write it as:
135*10^-3*10^3/10^3 watts=135*10^-6 kilowatts
135*10^-6 kilowatts= 1.35*10^-4

so answer is A

135 milli watts = 135 * 10^-3 watts
1 kilo watts = 10^3 watts

135 milli watts in killo watts

=135 * 10^-3 * 10^3 watts

(since 10^3 watts can be written as killo watts)

=135 * 10^-3 * killo watts

= 135 * 10^-3 KW

Anand said: (Jul 20, 2011)  
1 milliwatt=10^-3 watt.
135 milliwatt=0.135watt.
1kilowatt=1X10^3watt=1000 watt.
so the answer is in KW.
0.135Watt=1.35X10^-4 KW.(0.135/1000=0.000135watts)
so 0.000135watts=1.35X10^-4 Kilowatts

Keerthi said: (Sep 4, 2011)  
1kw=10^3 w
1kw=10^6 mw
1mw=10^-6 kw
135 mw=135*10^-6
135 mw=1.35*10^-4
so ans is A.

Rama Krishna said: (Dec 1, 2011)  
135mw=0.135w
1kw=1000w
1w=0.001kw
0.135 in kw =0.135/1000=0.135*10^-3=1.35*10^-4
so ans is a

1 Milli watts=1*10^-3
135 milli watts=0.135watts
1 k watts=1*10^3watts
0.135 watts= 0.135*10^-3 kilo-watts = 1.35*10^-4 kilo-watts.

Thufel Ahamed.N said: (Mar 12, 2012)  
135 milliwatts = 135 * 10^-3Watts

= 135 * 10^-3*(10^3*10^-3)watts
= 135 * 10^-3*10^-3*10^3 watts
= 135 * 10^-3*10^-3 killowatts
= (135 * 10^-2)*10^-4 killowatts
= 1.35*10^-4 killowatts

Therefore, answer 'A' is the correct answer.
Thank you!

1 millwatts=10^-3
1 k watts =10^3
135 convertd to mW thn 0.135
0.135*10^-3=1.35*10^-4

Vikrant said: (Jun 19, 2012)  
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.

Sayem, Diu said: (Nov 23, 2012)  
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

Uttam Kumar said: (Dec 9, 2012)  
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.

Faraz said: (Dec 13, 2012)  
135miliwatt=135/1000watts.
1watt=1/1000kwatt.

Therefore;

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

Akula Upender said: (Dec 27, 2012)  
135milliwatts=135*10^-3=.135watts and 1kw=1000watts.

So 1watt=1/1000=0.001 kw.

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

Vaibhav Khatavkar said: (Dec 27, 2012)  
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.

Indrajeet said: (May 27, 2013)  
We know,

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

Which is equal to option (A).

Vigneshb said: (Oct 13, 2013)  
1.35 *10^-4 kW.

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

1.35 *10^-1W.

So 135 mW.

Suresh said: (Feb 19, 2014)  
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.

Aman.Samyal said: (May 23, 2014)  
1mW = 0.001W.
1W = 0.001KW.
Therefore, 1mW = .000001 kW.

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

Prince Janesh Unique said: (Jul 30, 2014)  
First understand the logic principles ------>

0 --------> Milliwatts.
10 --------> Watts.
1000 -------> K.watts.

Conversions ------------------------->

135 milliwatts = 13.5 watts (135/10=13.5).
Now 1 K.W = 1000 watts.
1. watts = 0.001 kW.

135 m.W = 13.5 Watts = 13.5*0.001 kW.
= 1.35*0.00001kW.
= 1.35*10^-4.

Sorry friends still I can't understand. Please explain me clearly.

Ubhale said: (May 22, 2015)  
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.

Mohan said: (Jun 1, 2015)  
Consider that we have 1 milliwatt.

Now,

=> 1 milliW = 1*10^-6 KW.
=> 135 milliW = x KW.
=> (cross multiplying above).

x = 135*10^-6 KW.

x = 1.35*10^-4 KW (shifting upto 2 decimal points).

Tandel Hiren said: (Aug 9, 2015)  
1000 mw = 1 w.
135 mw = 0.135 w.

So 1000 w = 1 kw.
0.135 w = 1.35*10-4.

Am very impressed wit this workings, and it improved me.

Vedasri T said: (Sep 7, 2015)  
Thank you for explanation, good.

Darshit Shah said: (Nov 2, 2015)  
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.

Peekay said: (Mar 29, 2016)  
The most important term here is 1mW = 1000W.

Vimukth John said: (Jul 4, 2016)  
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.

Md Jakir Hosen said: (Aug 28, 2016)  
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.

Vipin Verma said: (Sep 5, 2016)  
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.

Devarajan said: (Nov 19, 2016)  
135 milliwatt =135 * 10^-3 watts.
Numerically, 1 watt = 1/1000 KW,
Therefore, (135 * 10^-3) watts = (135 * 10^-3)/1000,
= 135 * 10^-6 or 1.35 * 10^-4.

Kavya said: (Feb 15, 2017)  
I think option b is the right one.

Himansu said: (Mar 3, 2017)  
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.

Saritha said: (May 27, 2017)  
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.

Super Sid said: (Jul 15, 2017)  
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.

Prakash Koli said: (Aug 16, 2017)  
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.

Basant Dev said: (Nov 9, 2017)  
1kw=10^3w,
1kw=10^6mw,
So,135mw = 135x10^-6 = 1.35x10^-4kw.

Shilpashree. S said: (Jan 29, 2018)  
1000watts=1kw.
1milliwatts=?
So,1 milliwatts=10^-6kw.
So 135mw=135x10^-6KW=1.35X10^-4KW.
