To help compare different orders of magnitude this page lists lengths between 100 m and 1 km. See also lengths of other orders of magnitude.

• Shorter distances

• 100 m is equal to:
  • wavelength of the highest Mediumwave radio frequency, 3 MHz
  • 328 feet
  • side of square of area 1 hectare
  • the distance a very fast human being can run in about 10 seconds
• 105 m -- length of a soccer field
• 109.73 m -- total length of an American football field (120 yards, including the end zones)
• 112.34 m -- height of the world's tallest tree, a Coast redwood
• 128.1 m -- height of the world's tallest roller coaster, the Top Thrill Dragster at Cedar Point near Sandusky, Ohio, USA
• 137 m -- height of the Great Pyramid of Giza
• 168 m -- height of the Bungsberg, highest point in Schleswig-Holstein, Germany
• 187 m -- shortest wavelength of the broadcast radio AM band, 1600 kHz
• 193 m -- the approximate length of New Jersey State Highway 59
• 244 m -- height of the City Gate building in Israel
• 300 m -- height of the Eiffel Tower
• 304.8 m -- 1000 feet
• 310 m -- maximum depth of Lake Geneva
• 324 m -- total height of the Eiffel Tower including TV-antenna
• 328 m -- Auckland's Sky Tower, the tallest free-standing structure in the Southern Hemisphere
• 340 m -- distance sound travels in air at sea level in one second; see speed of sound
• 341 m -- height of the world's tallest bridge, the Millau Viaduct
• 390 m -- height of the Empire State Building
• 417 m -- height of the World Trade Center buildings before the September 11th Terrorist Attacks
• 443 m -- height of the Sears Tower, the tallest skyscraper in the United States

• 541 m -- (1,776 ft) -- height of the planned Freedom Tower at the World Trade Center site
• 553.33 m -- height of the CN Tower, the world's second tallest free-standing land structure
• 555 m -- longest wavelength of the broadcast radio AM band, 540 kHz
• 1 km = 0.62 miles
• 1 km -- wavelength of the lowest medium wave radio frequency, 300 kHz

• Longer distances
