Coordinate Converter

Thanks for that - just hope I can find it next time I need it.

Even easier to write the formulae on a little card and keep it in the sat-nav carry case until you're so used to converting that you don't need to refer to it.

The formulae are simple and are as follows:

To convert Degrees, Minutes & Seconds to Degrees, Minutes

Example: 46°9'57" = 46° and (9+(57/60))' = 46°9.950'

To convert Degrees, Minutes to Decimal Degrees

Example: 46°9.950' = 46. and (9.950/60)° = 46.1658°

To convert Degrees, Minutes & Seconds to Decimal Degrees

Example: 46°9'57" = 46. and ((9/60) + (57/3600))° = 46.1658°

To convert Decimal Degrees to Degrees, Minutes, Seconds

Example: 46.1658° = 46° and (0.1658 x 60)
= 46° and (9.948)
= 46°9' and (0.948 x 60)
= 46°9' and (56.88) - rounds up to 57
= 46°9'57"
 
Obvious really - if you just remember that there are 60 seconds in a minute and 60 minutes in a degree. I think I've got it!:)
 
I don't have a problem as my Sat Nav seems to accept all sorts of coordinates but I'd never remember any formula unless I was using it regularly also I'd never find the piece of paper I wrote it on after a few days
