Yard per Second to Millimeter per Minute

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

1 yd/s = 0.9144 m/s = 3.29 km/h = 2.045 mph = 3 ft/s.

To ft/s: × 3. To m/s: × 0.9144. To mph: × 2.045.

Sprint speeds in track and field (10–12 yd/s for elite sprinters), projectile velocities, and some fluid flow measurements.

Usain Bolt peak: ~13.5 yd/s. NFL wide receiver sprint: ~11 yd/s. Baseball thrown: ~40–45 yd/s.

Confusing with ft/s — yd/s is 3× faster. Mixing up with mph.

1 yd/s = 3 ft/s = 0.9144 m/s. Multiply by ~2 to get approximate mph.

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.
