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

Distances shorter than 1 hm

[edit] Conversions

1 hm is equal to:

• 328 feet
• one side of a 1 hectare square
• a fifth of a modern li, a Chinese unit of measurement
• 100 metres

[edit] Wavelengths

• 1.0 hm — wavelength of the highest mediumwave radio frequency, 3 MHz
• 1.87 hm — shortest wavelength of the broadcast radio AM band, 1600 kHz
• 5.55 hm — longest wavelength of the broadcast radio AM band, 540 kHz
• 10.00 hm — wavelength of the lowest mediumwave radio frequency, 300 kHz

[edit] Sports

• 1.00 hm — the distance a very fast human being can run in about 10 seconds
• 1.00 hm — length of a Canadian football field
