Centimeter per Minute to Kilometer per Second

Centimeter per minute measures distance in centimeters traveled over one minute. Used for small-scale, slow-moving processes.

1 cm/min = 0.01 m/min = 0.0001667 m/s = 0.0006 km/h.

To m/s: ÷ 6,000. To m/min: ÷ 100. To mm/min: × 10.

Snail movement (1–2 cm/min), slow laboratory stirrers, small conveyor systems, and plant growth measurements (fast-growing plants).

Garden snail: ~1 cm/min. Sloth movement: ~2 cm/min. Fast-growing bamboo shoots: up to 1.5 cm/min during peak growth.

Confusing with cm/s (60× faster) or cm/h (60× slower).

100 cm/min = 1 m/min. Good for measuring small creatures or slow mechanical processes.

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.
