Earth's Velocity to Foot per Minute

Earth's orbital velocity around the Sun is approximately 29,765 m/s (29.8 km/s), the speed at which our planet travels through space.

v = 2πr/T where r is Earth's orbital radius (~150 million km) and T is one year. Result: ~29.8 km/s.

To km/h: × 3,600. To mph: × 66,600. 29.8 km/s = 107,280 km/h = 66,660 mph.

Interplanetary mission Δv calculations, understanding Earth's motion, and cosmic velocity references.

We're all traveling at ~30 km/s around the Sun right now. In one second, Earth moves 30 km — about 19 miles!

Forgetting about Earth's motion when calculating interplanetary trajectories — it provides free velocity!

~30 km/s around the Sun. We travel 940 million km per year at this speed. Missions to other planets add/subtract from this.

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.
