Earth's Velocity to Mile per Minute

Earth's orbital velocity around the Sun is approximately 29,765 m/s (29.8 km/s), the speed at which our planet travels through space.

v = 2πr/T where r is Earth's orbital radius (~150 million km) and T is one year. Result: ~29.8 km/s.

To km/h: × 3,600. To mph: × 66,600. 29.8 km/s = 107,280 km/h = 66,660 mph.

Interplanetary mission Δv calculations, understanding Earth's motion, and cosmic velocity references.

We're all traveling at ~30 km/s around the Sun right now. In one second, Earth moves 30 km — about 19 miles!

Forgetting about Earth's motion when calculating interplanetary trajectories — it provides free velocity!

~30 km/s around the Sun. We travel 940 million km per year at this speed. Missions to other planets add/subtract from this.

Mile per minute measures the number of statute miles traveled in one minute. Used for very high speeds in imperial units.

1 mi/min = 60 mph = 96.56 km/h = 26.82 m/s.

To mph: × 60. To km/h: × 96.56. To m/s: × 26.82.

Aircraft speeds (commercial jets: 8–10 mi/min), high-speed trains, missile velocities, and meteor observations.

Commercial jet cruise: ~9 mi/min (540 mph). Military jet: 15–25 mi/min. Space shuttle reentry: ~300 mi/min.

Confusing with mph — 1 mi/min is 60 times faster than 1 mph.

Simple conversion: mi/min × 60 = mph. Example: 10 mi/min = 600 mph. Good for aviation mental math.
