Foot per Second

ft/s

Feet per second (ft/s) is used in some US engineering, ballistics (bullet velocity) and older US physics textbooks. Typical handgun muzzle velocity: 1000–1400 ft/s. Rifle muzzle velocity: 2500–3500 ft/s.

Real-world: 9mm bullet muzzle velocity: ~1150 ft/s. .308 rifle: ~2700 ft/s. Free fall terminal velocity: ~195 ft/s.

Beaufort Scale

Bft

The Beaufort scale is an empirical wind-force scale from 0 (calm) to 12 (hurricane). Created by Francis Beaufort in 1805, it correlates wind force with observed effects on sea or land. Force 8 (34–40 knots) is a gale; force 12 is above 64 knots.

Real-world: Force 5 (fresh breeze): 17–21 knots, white-caps form. Force 8 (gale): 34–40 knots. Force 12: 64+ knots.

Tips & common mistakes

Quick tips

1 ft/s = 0.3048 m/s = 1.097 km/h = 0.682 mph.
Multiplying ft/s by 0.682 gives mph.
US engineering often uses ft/s; metric countries use m/s.

Avoid these

Confusing ft/s with fps (frames per second in video/gaming).
Mixing ft/s with mph without conversion.
Using ft/s instead of m/s in international scientific contexts.

Frequently asked questions

How many Beaufort in a foot per second?

One foot per second equals 0.3048 Beaufort.

How do I convert feet per second to Beaufort?

Multiply the foot per second value by 0.3048 to get the equivalent in Beaufort.

What is 100 feet per second in Beaufort?

100 feet per second equals 30.48 Beaufort.

Is a foot per second bigger than a beaufort scale?

No. 1 foot per second equals 0.3048 Beaufort, so one foot per second is smaller.

How to convert feet per second to Beaufort without a calculator?

Multiply by 0.3 for a quick estimate; use a calculator for precise results.
