About converting Feet to Nautical Miles
Feet (ft) and Nautical Miles (nmi) are both units of length, so converting between them is a single multiplication: multiply your Feet figure by 0.0001646. Ten Feet comes to 0.001646 Nautical Miles, and a hundred works out at 0.01646 Nautical Miles.
Rule of thumb: going from Feet to Nautical Miles divides, so the figure always shrinks — it takes about 6,076.12 Feet to make a single Nautical Mile. If your answer came out bigger, you have the conversion the wrong way round.
What is a Foot?
A foot is twelve inches, or exactly 0.3048 meters. The name is not a metaphor — it descends from body-based measurement, though a real foot is rather shorter than the unit. Despite the world largely going metric, the foot is stubbornly entrenched in two places worth knowing about: American building construction, where lumber and floor plans are dimensioned in feet and inches, and international aviation, where altitude is reported in feet almost everywhere on Earth regardless of what the country uses on the ground.
What is a Nautical Mile?
A nautical mile is exactly 1,852 meters, and unlike every other unit here it was chosen to mean something geographically: it is one minute of latitude, one sixtieth of a degree. That is enormously convenient at sea and in the air, because a navigator can read distance straight off a chart’s latitude scale with dividers and no arithmetic. It is also the parent of the knot — one nautical mile per hour — which is why ships and aircraft report speed in knots rather than km/h.
To put both in perspective: a typical room ceiling is about 8 feet high, while a nautical mile is one minute of latitude on any chart.
