Question

How do you convert `0.45^circ` to `D^circM'S''` form?

Answer 1

`0.45^o=0^o27'0''`

Explanation:

In `D^oM'S''` "form, one degree is equivalent to `60` minutes and each minute is equivalent to `60` seconds.

As such, `0.45^o` is equivalent to `0.45xx60=27'`

As there are no fractional minutes, number of seconds are `0`

and `0.45^o=0^o27'0''`

Note - Had we have `0.455^o` this would have been equivalent to `0.455xx60=27.3'` and then `0.3'` would have been equivalent to `0.3xx60=18''` and `0.455^o=0^o27'18''`
