Mile per Minute to Kilometer per Second

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.

Kilometer per second measures how many kilometers an object travels in one second. Used for very high-speed phenomena like spacecraft, asteroids, and planetary motion.

1 km/s = 1,000 m/s = 3,600 km/h. There are 1,000 meters in a kilometer.

To m/s: × 1,000. To km/h: × 3,600. To mph: × 2,237.

Earth's orbital speed: 29.78 km/s. Moon's orbital speed: 1.02 km/s. Space shuttle orbital speed: 7.8 km/s. Meteor entry: 11–72 km/s.

Solar system escape velocity: 42 km/s. Voyager 1 speed: 17 km/s. Fastest star (S4714 near black hole): 24,000 km/s (8% light speed).

Underestimating the scale — 1 km/s is 3,600 km/h, extremely fast. Confusing with m/s (1000× smaller).

Think of km/s as 'space speeds.' Earth orbits at ~30 km/s. To escape Earth: 11.2 km/s. Moon orbit: ~1 km/s.
