To m/s: ÷ 1,000. To cm/s: ÷ 10. To km/h: × 0.0036.
1 mm/s = 0.001 m/s = 0.0036 km/h = 0.06 m/min.
For example, 1 Millimeter per Second (mm/s) = 3.937007874 Yard per Hour (yd/h).

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.
Yard per hour measures distance in yards traveled over one hour. Rarely used except in specialized contexts.
1 yd/h = 0.000254 m/s = 0.0009144 km/h = 0.9144 m/h.
To yd/min: ÷ 60. To ft/h: × 3. To m/h: × 0.9144.
No common modern applications. Might appear in some historical documents.
No notable facts — too rarely used.
Even existing is a mistake — use m/h, ft/h, or mph instead.
1,760 yd/h = 1 mph. Extremely uncommon. Better to use other units.
