Kilometer per Minute to Kilometer per Second

Kilometer per minute measures how many kilometers are traveled in one minute. It's a less common but useful speed unit for high-speed contexts.

1 km/min = 60 km/h = 16.667 m/s. There are 60 minutes in an hour.

To km/h: × 60. To m/s: × 16.667. To mph: × 37.28.

Describing meteor speeds, high-speed rail in casual conversation, or military projectile velocities.

Earth's orbital speed: 1,800 km/min. Escape velocity: 40 km/min. Fastest manned aircraft (X-15): 6.7 km/min.

Confusing with km/h — 1 km/min is 60 times faster than 1 km/h, not the same.

Easy conversion: km/min × 60 = km/h. Example: 2 km/min = 120 km/h. Useful for mental math with fast speeds.

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.
