If you stretch it a bit we have five - Sweden uses the "mil" which represents ten kilometers. The Swedish "mil" started off 1699, representing 6000 fathoms or 10,7 km. The "mil" was 1/2 of the king's stipulated max distance to between inns with horses for change etc. The "mil" survived when Sweden finally went metric in 1899, but was adjusted accordingly to signify 10,0 km. To this day we tend to talk about travelling distances in "mil" rather than kilometers.
