Yard per Minute to Millimeter per Second

Yard per minute measures distance in yards traveled in one minute.

1 yd/min = 0.01524 m/s = 0.05486 km/h = 0.9144 m/min.

To yd/s: ÷ 60. To ft/min: × 3. To m/min: × 0.9144.

American football player speeds (50–120 yd/min), slow boat speeds, and some industrial processes.

NFL running back: 100–120 yd/min sprint. Average walking: 50 yd/min.

Confusing with yd/s (60× faster) or mph.

~30 yd/min = 1 mph. Used occasionally in American sports contexts.

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.
