To ft/s: × 3. To m/s: × 0.9144. To mph: × 2.045.
1 yd/s = 0.9144 m/s = 3.29 km/h = 2.045 mph = 3 ft/s.
For example, 1 Yard per Second (yd/s) = 1.776315789 Knot (UK) (kt (UK)).

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.
The UK knot is a historical variation of the knot based on the British nautical mile (6,080 feet) rather than the international nautical mile (6,076.12 feet).
1 UK knot ≈ 1.853184 km/h = 0.5148 m/s. Slightly faster than the international knot (1.852 km/h).
To international knots: × 1.00064. To km/h: × 1.853. To m/s: × 0.5148.
None in modern use. Only relevant for interpreting historical British naval records.
The difference between UK and international knots is only 0.064% — barely noticeable but important for precise navigation.
Assuming all old British ship logs use the same knot as today — they don't, but the difference is tiny.
Historical only. Effectively identical to modern knot. Only matters for historical maritime research.
