Kilometer per Minute to Foot per Minute

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.

Foot per minute measures distance in feet traveled in one minute. Common in US industrial and HVAC applications.

1 ft/min = 0.00508 m/s = 0.01829 km/h = 0.3048 m/min.

To ft/s: ÷ 60. To m/s: × 0.00508. To mph: ÷ 88.

HVAC duct air velocity (600–2,000 fpm), conveyor belts (50–300 fpm), elevator speeds (200–1,500 fpm), and escalators (90–120 fpm).

Typical HVAC duct: 800–1,200 fpm. High-rise elevator: 1,000 fpm. Airport moving walkway: 140 fpm.

Confusing ft/min with ft/s — ft/min is 60× slower. Mixing fpm with mph.

60 ft/min = 1 ft/s. ~88 ft/min = 1 mph. Essential for HVAC calculations in the US.
