On my the longitude changes as I move. what is the distance between each full number on the gps?

Question

I just want to know if you can equate distance (accurately) when walking and watching the longitude numbers change

Answer 1

Unlike lines of latitude, which remain the same distance apart all over the Earth, lines of longitude are farther apart at the equator and come together at the poles.  For this reason degree length changes depending on your latitude.  If you are moving directly east-west and you know your latitude, you can calculate degree length.

Latitude________Surface distance per 1° change in longitude

0°_____________111.320 km

15°____________107.551 km

30°____________96.486 km

45°____________78.847 km

60°____________55.800 km

75°____________28.902 km

90°____________0.000 km

I think it's easier just to get a pedometer...
