Millimeter per Minute to Millimeter per Second

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.

Millimeter per second measures distance in millimeters traveled in one second. Used for small-scale movements and precise measurements.

1 mm/s = 0.001 m/s = 0.0036 km/h = 0.06 m/min.

To m/s: ÷ 1,000. To cm/s: ÷ 10. To km/h: × 0.0036.

Vibration measurements (machinery typically 0.1–50 mm/s RMS), small motor speeds, precision linear actuators, and tape/film transport speeds.

Machinery vibration: >10 mm/s indicates problems. Seismic activity: 0.001–100 mm/s. CD/DVD read head: 1.2–1.4 mm/s linear velocity.

Confusing mm/s with cm/s (10× different) or m/s (1000× different).

1,000 mm/s = 1 m/s. Very common in vibration analysis. 10 mm/s RMS is a typical machinery vibration threshold.
