Convert minute per mile to meters per minute

Runners think in pace, minutes per kilometre or per mile, which is the reciprocal of speed: 5:00 min/km is 12 km/h, 6:00 min/km is 10 km/h, and 8:00 min/mile is 12.1 km/h. A 4-hour marathon needs 5:41 min/km, a 25-minute 5 km 5:00 min/km. Swimmers use seconds per 100 m; treadmills usually display km/h or mph, so the conversion comes up on every gym visit. Note that pace is the only unit here where a smaller number means faster.

The SI unit of speed converts simply: 1 m/s is exactly 3.6 km/h, about 2.24 mph or 1.94 knots. A brisk walk is 1.5 m/s, a sprinter peaks at 12, sound travels at 343 m/s and a satellite in low orbit at 7.7 km/s. Weather services in the Nordic countries, Russia, Japan and China give wind speeds in m/s, where a strong breeze (Beaufort 6) is 11–14 m/s and a storm starts at 25; lifts are rated in m/s too, the fastest reaching 20. Metres per minute is the unit of conveyor belts and machining feeds.
