To m/s: × 0.3048. To km/h: × 1.097. To mph: × 0.682. To knots: × 0.592.
1 ft/s = 0.3048 m/s exactly (by definition of the international foot). 1 ft/s = 0.6818 mph.
For example, 1 Foot per Second (ft/s) = 20 Yard per Minute (yd/min).

Foot per second measures the number of feet traveled in one second. Commonly used in engineering, ballistics, and some sports in the United States.
1 ft/s = 0.3048 m/s exactly (by definition of the international foot). 1 ft/s = 0.6818 mph.
To m/s: × 0.3048. To km/h: × 1.097. To mph: × 0.682. To knots: × 0.592.
Bullet velocities (handgun: 800–1,200 ft/s; rifle: 2,500–4,000 ft/s), waterfall flow rates, industrial conveyor speeds, and skydiving terminal velocity (120 ft/s).
Speed of sound: 1,125 ft/s at sea level. Free fall: 32 ft/s² acceleration. Skydiver terminal velocity: 120 ft/s. Baseball pitch: 132 ft/s (90 mph).
Confusing ft/s with mph — 1 ft/s is only 0.68 mph, not 1 mph. Also, mixing up ft/s and ft/min in HVAC calculations.
1 ft/s ≈ 0.3 m/s or ≈ 1.1 km/h. Quick check: 100 ft/s ≈ 70 mph. Multiply ft/s by 0.68 for approximate mph.
Yard per minute measures distance in yards traveled in one minute.
1 yd/min = 0.01524 m/s = 0.05486 km/h = 0.9144 m/min.
To yd/s: ÷ 60. To ft/min: × 3. To m/min: × 0.9144.
American football player speeds (50–120 yd/min), slow boat speeds, and some industrial processes.
NFL running back: 100–120 yd/min sprint. Average walking: 50 yd/min.
Confusing with yd/s (60× faster) or mph.
~30 yd/min = 1 mph. Used occasionally in American sports contexts.
