# If the Earth was flat, what unit of measurement would distances between geographic points be represented as?

A whole lot of abstraction- given two longitude/latitude points given from a GPS, I'm using the Pythagorean distance formula to find the distance between them. What unit of length would the distance be? Kilometers? Miles?

Take your pick: en.wikipedia.org/wiki/Category:Units_of_length ... myself I would probably pick beard-seconds. So what's your real question? – blah238 Oct 4 '12 at 0:41
what do you mean, IF the earth was flat...... – Stephen Lead Oct 4 '12 at 3:14

@Brad, actually it would be whatever angular units the GPS unit was set to. Probably decimal degrees but could easily be a radian, gradian or mil. – blah238 Oct 4 '12 at 5:05
To the OP: Have you already considered why you are using the Pythagorean distance formula instead of a more suitable formula given that the earth is in fact not flat? – blah238 Oct 4 '12 at 5:14
