Convert Orbital Speed (ISS) to Kilometres per Minute

Convert Orbital Speed (ISS) (v_orb) to Kilometres per Minute (km/min) instantly and accurately.

Conversion Formula

km/min = v_orb × 459.6

About Orbital Speed (ISS)

The ISS orbits at ~408 km altitude at ≈7,660 m/s (27,576 km/h) - the practical LEO benchmark. At this speed it completes one orbit in 92.68 min (15.5 orbits per day), giving astronauts 16 sunrises and sunsets every 24 hours. Delta-v to reach LEO from Earth's surface is ~9,400 m/s (with gravity and drag losses). GEO at 35,786 km requires only ~3,075 m/s per Kepler's third law. 1 ISS speed ≈ 7,660 m/s.

About Kilometres per Minute

A kilometre per minute (km/min) = 50/3 m/s ≈ 16.667 m/s. F1 cars at Monza average ~4.33 km/min in qualifying. High-speed trains (TGV, ICE) cruise at 2.5-3.5 km/min. Subsonic military jet trainers fly at 3-7 km/min; combat aircraft cruise at 7-10 km/min. Dead-reckoning navigation: elapsed minutes × km/min = distance. 1 km/min = 60 km/h = 37.28 mph.
