Yard per Second to Centimeter per Second

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.

Centimeter per second measures distance in centimeters traveled in one second. Common for small-scale movements and flows.

1 cm/s = 0.01 m/s = 0.036 km/h = 0.6 m/min.

To m/s: ÷ 100. To km/h: × 0.036. To mm/s: × 10.

Stream/river surface flow (10–200 cm/s), blood flow velocity in arteries (10–100 cm/s), small machine movements, and insect flight speeds.

Housefly speed: ~200 cm/s. Blood in aorta: ~40 cm/s. Small stream flow: 30–100 cm/s. Ant running: 1–3 cm/s.

Confusing cm/s with m/s — off by a factor of 100. Mixing up with mm/s.

100 cm/s = 1 m/s. Good for water flow, blood flow, and small animal speeds. Divide by 100 to get m/s.
