How fast is 216.83 feet per second?

Sort Order:
Closest first | Highest first | Lowest first

It's about nine-tenths as fast as a Skydiver (headfirst).
In other words, 216.83 feet per second is 0.92 times the speed of a Skydiver (headfirst), and the speed of a Skydiver (headfirst) is 1.1 times that amount.
(Head-to-Earth orientation or standing, average conditions, terminal velocity)
A head-to-Earth or standing-oriented skydiver's terminal velocity assuming average conditions is about 240 feet per second. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 46 seconds.
It's about four-fifths as fast as a Helicopter.
In other words, 216.83 feet per second is 0.838 times the speed of a Helicopter, and the speed of a Helicopter is 1.19 times that amount.
(for AH-64A Apache, a.k.a. Hughes Model 77) (maximum cruise speed)
The AH-64 helicopter, one of the primary helicopters used by the United States Army, flies at a top cruise speed of 259 feet per second. The AH-64 is the primary military helicopter of several nations including the United States, the United Kingdom, Israel, Japan, and the Netherlands.
It's about one-and-one-fifth times as fast as a Tornado.
In other words, 216.83 feet per second is 1.197074 times the speed of a Tornado, and the speed of a Tornado is 0.8353702 times that amount.
(EF2) (wind speed range average)
According to the Enhanced Fujita scale implemented by the US National Oceanographic and Atmospheric Administration, a "significant" tornado has an Enhanced Funjita scale classification of EF2 and is characterized by wind gust speeds between 161.3333 feet per second and 200.9333 feet per second. The largest recorded tornado — an F4 event occurring in Nebraska in May, 2004 — was almost 4.02 km (2.5 mi) across.
It's about one-and-one-fifth times as fast as a Skydiver (belly-to-earth).
In other words, the speed of a Skydiver (belly-to-earth) is 0.83 times 216.83 feet per second.
(Belly-to-Earth orientation, average conditions, terminal velocity)
A belly-to-Earth oriented skydiver's terminal velocity is about 170 feet per second. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 60 seconds.
It's about three-fourths as fast as a Lamborghini Gallardo.
In other words, the speed of a Lamborghini Gallardo is 1.4 times 216.83 feet per second.
(for Gallardo LP 550-2, a.k.a. Valentino Balboni, 2009 model)
The Lamborghini Gallardo LP550-2 model Gallardo has a top speed of 290 feet per second. The Gallardo can reach speeds of 91 feet per second in just 3.9 seconds.
It's about three-fourths as fast as The TGV (train).
In other words, the speed of The TGV (train) is 1.4 times 216.83 feet per second.
(Train à Grande Vitesse) (for SNCF TGV Réseau, a.k.a. "Network" model, a.k.a. TGV-R) (maximum speed)
The TGV Réseau sets have a top speed of 290 feet per second. The train is capable of travelling the 425 km (264 mi) distance from Paris to Lyon in East-Central France in about two hours.
It's about three-fourths as fast as an Arrow (archery).
In other words, 216.83 feet per second is 0.737 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 1.357 times that amount.
(250 g arrow fired from 60#/28" bow)
A 250 gram arrow will reach speeds of approximately 294.2 feet per second when fired from a 60-lb, 28-inch draw bow . Archeological evidence from the Ahrensburg valley near Hamburg, Germany indicates that arrows have been used since at least 11 to 12,000 years ago.
