Merhale

Merhale was an Ottoman unit of length.

8 fersahs were equal to 1 merhale. Fersah was based on the distance covered by a horse in normal gait per hour. Exact definition was 5685 meters.^[1]

So 1 merhale can be converted to meters.^[2]

${\displaystyle 1\quad {\mbox{merhale}}=8\cdot 5685=45480\quad {\mbox{meters}}}$
