Conversion To Coordinates
7 Answers
Hi,
Can anyone help me convert the following into a set of useable coordinates please. The N 4303 will almost certainly be 51 and the E 80 will be 000
N 4303° 6114.54022' E 80° 31121.71636'.
Thank you

So 6114.54022' is the same thing as 101° 54.54022' 54.54022', and so the North coordinate is 4404° 54.54022'.
Still not perfectly useful, but we can say that every 360° you do a full turn, so we can say that, eg., 361° is the same as 1° from the point of view of coordinates. Hence we should keep subtracting off 360° until we get back to a number less than 360. we need to take 12 lots of 360 away from 4404, and can't take any more off, and you find that we are left with 84. So
N 4303° 6114.54022' = N 84° 54.54022'.
The same technique should work for the East coordinate.
[I should add that possibly I'm mistaken in reading 54.54022' as "54 and a half arc minutes", and that it should be read instead as "54 arcminutes, and 54 thousand and 22 arcseconds". If that's the case then 60 arcseconds = 1 arcminute and you can do the same trick as before to reduce all those arcseconds into arcminutes.]
