No answer description available for this question.

 Prashant said: (Jan 20, 2011) 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

 Karthik said: (Jul 9, 2011) 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

 Arulprakash said: (Feb 16, 2012) 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!

 Oviya said: (Mar 20, 2012) 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.

 Shadiq said: (Dec 5, 2014) 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.

 Samuel Timothy said: (Sep 1, 2015) 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.
