1,000 miles per hour
Speed: 1,609 km/h; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Earth equator rotational speed
Representative surface speed: 1,674 km/h; derived rounded anchor; range 1,674 km/h–1,678 km/h.
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.

- Comparing
- Speed ↔ Representative surface speed
- Relative size
- The rotational speed at Earth’s equator is about 1.04 times 1,000 miles per hour. The rotational speed at Earth’s equator is approximately 4.04% greater than 1,000 miles per hour.
How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 1,674 km/h for the rotational speed at Earth’s equator; the recorded range is 1,674 km/h–1,678 km/h.
- The rotational speed at Earth’s equator: This is a rounded comparison value; check the notes for its source and scope.
Speed is distance per unit time; it does not specify the total distance travelled.
