Discrepency in coordinates

[iFlyAllTheTime]

Surely, I can't be the only one who has noticed this but I couldn't find anything regarding this on the forums.

I planted a flag at KSC (on top of the VAB) so I could compare the coordinates when I hover my mouse in map view to the MechJeb and KER readouts.

The longitude for KSC shows up as E 285° 23' 07'' when I use the mouse in map view.

The longitude for KSC show up as -74.6xxxx in KER and

W 74° xx' xx'' in MechJeb

The longitude for launchpad are -74.5xxxxx in the debug menu accessible by Alt+F12

To me the modded and the debug coordinates make sense.

Aren't longitudes numbered 0° to 180° E and 180° W; making 360° of longitude?

What's up with the E 285° stuff?

Depends on how you pick a coordinate system. (0 to 360 or -180 to 180)

360 - 285 = 75
