Earth's Velocity to Millimeter 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.

Millimeter per minute measures small distances in millimeters traveled over one minute.

1 mm/min = 0.001 m/min = 0.0000167 m/s = 0.00006 km/h.

To m/s: ÷ 60,000. To cm/min: ÷ 10. To m/min: ÷ 1,000.

CNC machine feed rates (50–500 mm/min for cutting), 3D printer speeds, medical infusion pumps, and slow actuator movements.

3D printer typical: 40–150 mm/min. Slow drill feed: 10–100 mm/min. Medical IV drip: 1–50 mm/min (linear displacement).

Confusing with mm/s (60× faster) or cm/min (10× faster).

1,000 mm/min = 1 m/min. Very common in machining. Good for precision movements.
