How to convert 157 cs to seconds

              1.57 s

Solution:

                 Centisecond is equal to second as follow,

                        1 Second  = 100 centiseconds

Therefore, 157 cs is converted to seconds as,

                            100 cs  =  1 s

So,

                            157 cs  =  X s

solving and calculating for X,

                                  X  =  ( 157 cs * 1 s) / 100 cs

                                  X  =  1.57 s
