Speed Converter

Convert kilometres per hour, miles per hour, metres per second and knots in real time.

What it is

Speed Converter turns meters per second, kilometers per hour, miles per hour, knots and feet per second into each other as you type. 60 mph equal about 96.56 km/h and about 52.14 knots: useful for comparing road speed limits, vehicle specs, or weather and marine data given in different units. Knots (kn) are included, the nautical and aviation standard missing from several generic competitor converters, calculated on the same exact nautical mile (1852 m) shared with the length converter.

  • From m/s to knots: 5 units, including the nautical/aviation standard kn
  • 60 mph ≈ 96.56 km/h ≈ 52.14 knots: instant comparison across systems
  • Knots share the nautical mile with the length converter: 1 knot = 1 nautical mile per hour

How it works

#1
Pick the starting unit
Choose from m/s, km/h, mph, knots (kn) or ft/s.
#2
Type the value
Enter the number to convert: the result in the other unit appears instantly.
#3
Check the common table
Below the result you'll find standard multiples already converted, useful for comparing typical speeds (30, 60, 80 mph...).

Features

Knots, not just mph and km/h
The knot (kn), the international standard for sea navigation and aviation, is included and calculated on the exact nautical mile (1852 m): a unit missing from several generic competitor converters.
Instant comparison across systems
60 mph ≈ 96.56 km/h: useful for reading speed limits or vehicle specs given in a different unit than you're used to.
Common conversions table
Standard multiples (30, 60, 80, 120 mph...) already calculated below the result, for quick comparisons without a calculator.
Linked to length and time
Speed is distance divided by time: check the length converter and the time converter too for the values that make up a speed.

FAQ

About 52.14 knots (60 mph converted through meters per second, divided by the knot's 1852 m/3600 s factor).
The knot is tied to the nautical mile (1852 m), itself defined from one minute of arc of latitude: an international standard shared by nautical and aeronautical charts, independent of the metric or imperial system used on land.
About 96.56 km/h (60 × 1.609344).
1 ft/s equals 0.3048 m/s, about 0.682 mph: a unit used mostly in US technical and aeronautical contexts.
Divide the distance traveled by the time taken: convert the two values with the length converter and the time converter, then use this tool for the final speed unit.
