ft/s to m/s

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.

The meter per second is the SI derived unit of speed and velocity, defined as the distance traveled in meters over time in seconds. It represents how many meters an object moves in one second.

1 m/s = base unit. Direct relationship with distance (m) and time (s). Speed = distance ÷ time.

To km/h: × 3.6. To mph: × 2.237. To ft/s: × 3.281. To knots: × 1.944.

Walking speed (1.4 m/s average), running speed (elite sprinters reach 12.4 m/s), vehicle speeds in scientific contexts, and wind speed measurements.

Usain Bolt's top speed: 12.4 m/s (44.6 km/h). Cheetah speed: 29 m/s. Speed of sound at sea level: 343 m/s. Light: 299,792,458 m/s.

Confusing m/s with km/h — a common error when reading speedometers. Remember: multiply m/s by 3.6 to get km/h.

Quick conversion: 10 m/s ≈ 36 km/h. To visualize: 1 m/s means moving one big step per second. Multiply by 3.6 for km/h.
