              CONVERSION OF TIME


              The relationship between different units of time given below helps you for their conversion.

                  1 minute      = 60 seconds                        1 fortnight     = 2 weeks = 14 days
                  1 hour        = 60 minutes                        1 year          = 12 months

                  1 day         = 24 hours                          1 year          = 365 days
                  1 week        = 7 days                            1 leap year     = 366 days

              Conversion of Higher Units into Lower Units

              To convert higher units of time into lower units, we multiply.
              Example 1: Convert the following:

                    (a)  15 minutes into seconds                     (b)  8 minutes 52 seconds into seconds

                    (c)  2 hours 23 minutes 19 seconds into seconds

              Solution:
                    (a)  Since, 1 minute = 60 seconds

                         So, 15 minutes = (15 × 60) seconds = 900 seconds
