To yd/min: ÷ 60. To ft/h: × 3. To m/h: × 0.9144.
1 yd/h = 0.000254 m/s = 0.0009144 km/h = 0.9144 m/h.
For example, 1 Yard per Hour (yd/h) = 8.533513e-9 Earth's Velocity (vₑ).

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 Might appear in some historical documents.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.
Earth's orbital velocity around the Sun is approximately 29,765 m/s (29.8 km/s), the speed at which our planet travels through space.
v = 2πr/T where r is Earth's orbital radius (~150 million km) and T is one year. Result: ~29.8 km/s.
To km/h: × 3,600. To mph: × 66,600. 29.8 km/s = 107,280 km/h = 66,660 mph.
Interplanetary mission Δv calculations, understanding Earth's motion, and cosmic velocity references.
We're all traveling at ~30 km/s around the Sun right now. In one second, Earth moves 30 km — about 19 miles!
Forgetting about Earth's motion when calculating interplanetary trajectories — it provides free velocity!
~30 km/s around the Sun. We travel 940 million km per year at this speed. Missions to other planets add/subtract from this.
