Millimeter per Minute to Meter per Hour

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.

Meter per hour measures the distance in meters traveled over the course of one hour. It's a very slow speed unit used for measuring gradual processes.

1 m/h = 1/3600 m/s = 0.000278 m/s. Very small speed unit for very slow processes.

To m/s: ÷ 3,600. To km/h: ÷ 1,000. To ft/h: × 3.281.

Glacier movement (typically 10–200 m/h in fast glaciers), hair growth (0.0001 m/h), slow industrial processes, and scientific experiments.

Average glacier: 10–100 m/h. Tectonic plate movement: ~0.005 m/h. Bamboo (fastest growing plant): up to 0.091 m/h.

Confusing m/h with m/s — m/h is 3,600 times slower. Using it for normal speeds instead of km/h or m/s.

Remember: 1,000 m/h = 1 km/h. Useful for very slow processes. Think glaciers, not cars.
