How it works

1 nautical mile = 1,852 m exactly; 1 cable = 0.1 nm; 1 knot = 1 nm per hour. 1 fathom = 6 ft = 1.8288 m; 1 shackle of anchor cable = 15 fathoms (27.432 m). 1 bar = 14.504 psi = 100 kPa. 1 kW = 1.36 metric hp. 1 oil barrel = 158.99 litres.

Positions: 33° 51.408′ S = 33° 51′ 24.48″ S = −33.8568°. South latitudes and west longitudes are negative in decimal form.
