How fast is 0.045 miles per second?

Sort Order:
Closest first | Highest first | Lowest first

It's about as fast as a Skydiver (headfirst)
(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 0.045 miles 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 nine-tenths as fast as a Helicopter
In other words, 0.045 miles per second is 0.9180 times the speed of a Helicopter, and the speed of a Helicopter is 1.09 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 0.049 miles 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 four-fifths as fast as a Lamborghini Gallardo
In other words, 0.045 miles per second is 0.810 times the speed of a Lamborghini Gallardo, and the speed of a Lamborghini Gallardo is 1.20 times that amount.
(for Gallardo LP 550-2, a.k.a. Valentino Balboni, 2009 model)
The Lamborghini Gallardo LP550-2 model Gallardo has a top speed of 0.055 miles per second. The Gallardo can reach speeds of 0.017 miles per second in just 3.9 seconds.
It's about four-fifths as fast as The TGV (train)
In other words, 0.045 miles per second is 0.810 times the speed of The TGV (train), and the speed of The TGV (train) is 1.20 times that amount.
(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 0.055 miles 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 four-fifths as fast as an Arrow (archery)
In other words, 0.045 miles per second is 0.80760 times the speed of an Arrow (archery), and the speed of an Arrow (archery) is 1.2380 times that amount.
(250 g arrow fired from 60#/28" bow)
A 250 gram arrow will reach speeds of approximately 0.05572 miles 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.
It's about four-fifths as fast as a Porsche 911
In other words, 0.045 miles per second is 0.7920 times the speed of a Porsche 911, and the speed of a Porsche 911 is 1.260 times that amount.
(for Porsche 911 Type 997 GT2, 2007 model)
The Porsche 911 GT2 has a top speed of 0.0568 miles per second. It takes just 7.4 seconds for the GT2 to accelerate to 0.0278 miles per second.
It's about one-and-three-tenths times as fast as a Tornado
In other words, 0.045 miles per second is 1.3117410 times the speed of a Tornado, and the speed of a Tornado is 0.76234560 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 0.03055556 miles per second and 0.03805556 miles per second. The largest recorded tornado — an F4 event occurring in Nebraska in May, 2004 — was almost 4.02 km (2.5 mi) across.
