Earth equator rotational speed
Earth equator rotational speed is the velocity at which a point on the equator moves eastward due to Earth's rotation.
Also known as: equatorial rotation speed
How big is it?
1,674 km/h
Also 1,040 mph
Representative surface speed · derived rounded anchor
Typical recorded range: 1,674 km/h to 1,678 km/h.
A little perspective
Concorde is about 1.29 times larger on this measurement.
Concorde: Concorde was a supersonic passenger airliner developed by British and French manufacturers that could travel faster than the speed of sound.
Measurements, assumptions & sources +
Earth equator rotational speed
A point on Earth’s equator moves eastward at about 465.1 m/s relative to the rotation axis. Latitude reduces surface speed and this is distinct from Earth’s orbital motion.
The marked representative surface speed is calibrated. Unmeasured illustration details are representative.
Concorde
British Airways’ Concorde specification: 62.1 m long, 25.5 m span, 11.3 m high, 185 t maximum takeoff mass and about 2,160 km/h cruise. Operating mass and speed varied.

Why this measurement?
Why we use 1,674 km/h
For comparison, this page uses representative surface speed. This is labelled derived rounded anchor; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 1,674 km/h to 1,678 km/h.
