Default Antenna for Marine VHF

Conservative radio range on VHF is:
Nautical_Miles = 1.225 * sqrt(antenna_ht_feet)
Statute_Miles = 1.415 * sqrt(antenna_ht_feet)
km = 4.124 * sqrt(antenna_ht_feet)

Something is wrong with the km line above. Perhaps the antenna height
should be in meters? Or, the constant should be 2.278.
