Depends on if its statute miles or Nautical miles
25 statute miles is roughly 40km
25 Nautical miles is roughly 45km
all the australian charts are in nautical miles so i normally run in them
and Knots for air speed, on the ground its all metric same as you Raimo

Ferg,
One friend - a Learjet pilot who I respect - said his minimum is 50 km.
That is like your 25 miles.
