Aviation Converter
Convert distance, speed, and altitude for flight planning and navigation
Re-express a supplied distance, speed or height using its named units. A nautical mile and an international mile are different lengths; knots describe speed.

This page re-expresses supplied quantities. It does not determine route, range, clearance, separation or operational flight procedures.
Context
The international nautical mile is fixed at 1852 m by NIST footnote 20. The international mile is 1609.344 m and the international foot is 0.3048 m, as given by NIST revised definitions. A knot is one nautical mile per hour, as shown in NOAA’s knot definition.
The length measurement workflow explains these named length conventions. Select a speed converter for a speed and a length converter for a distance or stated height. The numerical conversion alone does not provide navigation or operational decisions.

Why this matters
Re-express a supplied nautical-mile distance
For a hypothetical 800 nmi quantity, multiply by 1852 m/nmi and divide by 1609.344 m/mi to obtain international miles.
Re-express a supplied speed
For a hypothetical 30-knot quantity, use the speed converter. A length converter cannot by itself express knots as mph.
Re-express a supplied height
For a hypothetical 35000 international feet, calculate 35000 × 0.3048 = 10668 m. This does not establish a clearance or an operational altitude.
Frequently asked
What is a hypothetical 800 nautical miles in international miles? →
800 × 1852 / 1609.344 ≈ 920.6236 mi at four decimal places. Use nautical miles to international miles.
What is a hypothetical 30 knots in mph? →
30 × 1852 / 1609.344 ≈ 34.5234 mph at four decimal places. Use knots to mph because the supplied quantity is speed.
Can a foot-to-meter conversion select an operational altitude? →
No. It re-expresses the supplied height using the international foot of 0.3048 m. Use feet to meters for that numerical conversion, keeping operational decisions separate.
Is a knot one nautical mile per hour? →
Yes. NOAA states 1 knot = 1 nautical mile per hour. The international nautical mile is 1852 m; that defines the speed unit without asserting a particular actual latitude arc length.
