Furlongs to Nautical Miles FAQ

  • One furlong equals approximately 0.1087 nautical miles. Since 1 furlong = 201.168 m and 1 NM = 1,852 m, divide 201.168 by 1,852.

  • One nautical mile contains approximately 9.206 furlongs.

  • No. Furlongs are strictly a land unit. At sea, distances use nautical miles, cable lengths, and fathoms. The two systems never mix.

Non-Frequently Asked Questions About Furlongs to Nautical Miles

Questions nobody should ask - but someone did.

  • The Channel at its narrowest is about 18.2 NM or about 166 furlongs. At racing pace, a horse could cover that in about 33 minutes of flat-out galloping. But horses cannot gallop on water, and the Channel is wet. Swimming the Channel takes about 10-14 hours for humans. Horses are faster on land but slower in the sea.

  • No. Nautical navigation uses nautical miles, cables (1/10 NM), and degrees. Nobody plots a course in furlongs. A furlong (0.1089 NM) is too small for ocean navigation and too agricultural for maritime charts. Keep furlongs on the racetrack.

  • The Atlantic is about 2,850 NM wide (New York to London). That is about 26,146 furlongs. A horse racing that distance at 12 seconds per furlong would take about 3.63 days of continuous galloping. Transatlantic horse racing: impractical but mathematically defined.
