World Radiocommunication Conference (WRC), organized under the auspices of the International Telecommunication Union (ITU), in agreement with various national amateur radio organizations and governing agencies like the FCC.
2.1 The Bands
In addition, within these bands, operation is limited based upon license class, so a Technician-licensed amateur has access to certain frequency ranges, a General class operator has additional permissions, and an Extra class operator has full privileges.
The Amateur Bands
For the HF or High Frequency bands, ARRL has a useful chart that can be downloaded from the site. There is also a good quality set of charts downloadable from this site:
There is one sheet for each band, and these are very easy to decipher at a glance.
Additional band info provided by KA3SGM :
The 60m band is 5 specific USB channels, which are currently Bandwidth Limited, Channelized, and Power Limited to 50 watts ERP, per ARRL chart specifications: General, Advanced, and Amateur Extra licensees may use the following five channels on a secondary basis with a maximum effective radiated power of 50 W PEP relative to a half wave dipole. Only upper sideband suppressed carrier voice transmissions may be used. The frequencies are 5330.5, 5346.5, 5366.5, 5371.5 and 5403.5 kHz. The occupied bandwidth is limited to 2.8 kHz centered on 5332, 5348, 5368, 5373, and 5405 kHz respectively.
70cm UHF is 420 to 450*, not 430 to 440. Heck, most 70cm FM repeaters operate in the 440MHz to 450MHz range, above what is referenced here. The lower end of the band is generally reserved to Weak Signal, CW, SSB, Moon Bounce, Satellite, and Amateur TV. * it is a shared allocation with the US Government/Military, so occasional interference close to US Military Installations are common.

5650-5925MHz is the 5cm Amateur band. The ARRL bandplan designates 5760.30-5760.40MHz for Propagation Beacons. Off-Shelf 802.11a WiFi Equipment operating in the 5.745~5.85GHz range falls into this category, so power amplifiers and High Gain antennas are allowed under FCC Part 97 rules, although any type of common WiFi encryption such as WEP or WPA is not allowed. Popular uses are Amateur High Speed Multi Media (HSMM) communications(Video, Voice and Data), referred to by some in the ARRL HSSM working group as part of the the 'Hinternet'.

Band Plan in Canada should be mentioned as well. Found at http://www.rac.ca/service/allband.htm and http://www.ic.gc.ca/epic/site/smt-gst.nsf/en/sf01226e.html
Divide the frequency into 300 to get the wavelength.
