Calculating distance in m light travels in 1yr, Physics

Assignment Help:

Example 1:How far in meters does light travel in one year?

Solution: 299,792,458m x 31,557,600s
=9.461 x 10 to the power of15

Question, while i understand the above, why can we not calculate as;

1s= 299,792,458 m
1m = above x60
1hr = above x60
1dy= above x60
1yr = above x365

why do we have to convert them into similar units?
Aren''t the number of seconds contained within a yr same as those in a day , min ?
