Yard per Second to Meter per Hour

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.

Meter per hour measures the distance in meters traveled over the course of one hour. It's a very slow speed unit used for measuring gradual processes.

1 m/h = 1/3600 m/s = 0.000278 m/s. Very small speed unit for very slow processes.

To m/s: ÷ 3,600. To km/h: ÷ 1,000. To ft/h: × 3.281.

Glacier movement (typically 10–200 m/h in fast glaciers), hair growth (0.0001 m/h), slow industrial processes, and scientific experiments.

Average glacier: 10–100 m/h. Tectonic plate movement: ~0.005 m/h. Bamboo (fastest growing plant): up to 0.091 m/h.

Confusing m/h with m/s — m/h is 3,600 times slower. Using it for normal speeds instead of km/h or m/s.

Remember: 1,000 m/h = 1 km/h. Useful for very slow processes. Think glaciers, not cars.
