Sort Order:
Closest first | Highest first | Lowest first

It's about forty times as fast as a Crocodile
In other words, the speed of a Crocodile is 0.028 times 350 kilometers per hour.
(American Crocodile, Crocodylus acutus) (swimming speed)
An American crocodile can reach speeds in the water of up to 10 kph. On land, larger crocodiles can "gallop" when fleeing danger at speeds of up to 20 kph.
It's about 50 times as fast as Michael Phelps
In other words, 350 kilometers per hour is 50.05 times the speed of Michael Phelps, and the speed of Michael Phelps is 0.01998 times that amount.
(at the Beijing Olympics, 2008; 200 m freestyle) (a.k.a. Michael Fred Phelps) (swimmer; 1985-)
Setting a world record, Michael Phelps swam the 200 m freestyle in 1:42.96 for an average speed of 6.993 kph. Phelps would go on to win nine gold medals individually in the 2008 Olympics - more than all but eight of the competing nations.
It's about 75 times as fast as Walking Pedestrians (in Manhattan)
In other words, the speed of Walking Pedestrians (in Manhattan) is 0.013 times 350 kilometers per hour.
(Manhattan; average speed; 8,978 person-sample)
A 2006 Study by the New York City Department of City Planning found that pedestrians in that city walk at an average rate of 4.70 kilometers per hour. Pedestrians wearing headphones, the study went on to find, walk at a slightly faster 5.10 kilometers per hour
It's about one-eightieth as fast as The Space Shuttle
In other words, 350 kilometers per hour is 0.012555 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 79.650 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 200 times as fast as an Iceberg
In other words, the speed of an Iceberg is 0.005 times 350 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-four-hundred-fiftieth as fast as a Meteor
In other words, the speed of a Meteor is 430 times 350 kilometers per hour.
(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.
It's about one-one-thousandth as fast as a bolt of Lightning
In other words, 350 kilometers per hour is 0.00099 times the speed of a bolt of Lightning, and the speed of a bolt of Lightning is 1,000 times that amount.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 350,000 kph when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
