How fast is 0.21 miles per minute?
It's about 85 times as fast as a Sloth
The speed of a Sloth is about 0.0025 miles per minute.
(for Brown-throated three-toed sloth, Bradypus variegatus)
The three-toed sloth moves along the ground at an average speed of 0.0025 miles per minute. Long thought to be lengthy sleepers, a 2008 study concluded that sloths sleep an average of only 9.6 hours per day.
It's about one-one-hundredth as fast as a Jet Fighter
The speed of a Jet Fighter is about 25 miles per minute.
(for Lockheed Martin F-16, a.k.a. Fighting Falcon, a.k.a. Viper) (maximum speed at altitude)
An F-16's maximum speed at altitude is approximately 25 miles per minute. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about one-one-hundred-fiftieth as fast as a Bullet (Rifle)
The speed of a Bullet (Rifle) is about 34.10 miles per minute.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 34.10 miles per minute. As the NATO rifle cartridge, it is used by the military forces of more than thirty-one countries, including use in the M16 series, M4 Carbine, HK-416, and M249 Squad automatic weapons used by the United States armed forces.
It's about one-one-thousand-five-hundredth as fast as The Space Shuttle
The speed of The Space Shuttle is about 288.70 miles per minute.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 288.70 miles per minute. During liftoff, the space shuttle accelerates to orbital speed in 8.5 minutes, consuming over 1.59 million kg (3.51 million lbs) of propellant in the process.
It's about one-seven-thousand-five-hundredth as fast as a Meteor
The speed of a Meteor is about 1,600 miles per minute.
(formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")
Small meteoroids enter the Earth's atmosphere at speeds between 410 miles per minute and 2,700 miles per minute, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 100 miles per minute.
It's about one-twenty-thousandth as fast as a bolt of Lightning
The speed of a bolt of Lightning is about 3,700 miles per minute.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 3,600 miles per minute when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about 0.00000002 times as fast as The Speed of Light
The speed of The Speed of Light is about 11,176,943.8230730 miles per minute.
(C) (in a vacuum)
The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures 11,176,943.8230730 miles per minute, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 7,451,295.88217310 miles per minute when passing through the glass of a typical window.
It's about 150,000,000 times as fast as Grass growing
The speed of Grass growing is about 0.00000000150 miles per minute.
(for Kentucky Bluegrass, Poa pratensis) (a.k.a. Smooth Meadow grass, a.k.a. Common Meadow grass) (Summer months, ideal growing conditions)
Kentucky Bluegrass, one of the most common grasses in North America, grows about 0.00000000160 miles per minute in the summer months under ideal conditions. When left un-mowed, Kentucky Bluegrass grows to heights of 60 to 90 cm (2 to 3 ft) and blossoms with a blue flower.
