How fast is 80 kilometers per hour?

Sort Order:
Closest first | Highest first | Lowest first

It's about one-fifteenth as fast as a Bullet (Handgun)
In other words, the speed of a Bullet (Handgun) is 17.30 times 80 kilometers per hour.
(for .40 Smith & Wesson 135 grain Sierra JHP, VV 3N37 powder, Fed. 100 primer, Remington case) (muzzle velocity)
A 0.40 caliber Smith & Wesson bullet has a muzzle a velocity of 1,380 kph. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
It's about one-thirtieth as fast as a Jet Fighter
In other words, the speed of a Jet Fighter is 30 times 80 kilometers per hour.
(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 2,400 kilometers per hour. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about 40 times as fast as an Iceberg
In other words, the speed of an Iceberg is 0.03 times 80 kilometers per hour.
(a.k.a. Berg) (Newfoundland iceberg average)
Moved by ocean currents and wind, icebergs can drift at speeds of about 2 kilometers per hour. The largest iceberg ever recorded was a found near Baffin Island, Nunavut and was estimated to be nine billion metric tons.
It's about one-fortieth as fast as a Bullet (Rifle)
In other words, 80 kilometers per hour is 0.0243 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 41.20 times that amount.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 3,294 kph. 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 350 times as fast as a Sloth
In other words, the speed of a Sloth is 0.003 times 80 kilometers per hour.
(for Brown-throated three-toed sloth, Bradypus variegatus)
The three-toed sloth moves along the ground at an average speed of 0.24 kph. 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-three-hundred-fiftieth as fast as The Space Shuttle
In other words, 80 kilometers per hour is 0.0028698 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 348.460 times that amount.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 27,877 kph. 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-two-thousandth as fast as a Meteor
In other words, 80 kilometers per hour is 0.00053 times the speed of a Meteor, and the speed of a Meteor is 1,900 times that amount.
(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 40,000 kph and 260,000 kph, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 10,000 kph.
