Unit of measurement of length equivalent to 100 metres.


  • The notation used is “hm” which represents “hectometre.”
  • One hectometre is equal to 100 metres and we write: 1 hm = 100 m.


You may have noticed that on most highways, between each kilometre, there is a boundary marker every 100 metres, or in other words, every hectometre. So, we can say that these signs are hectometric boundary markers.
