A hill is classified as a Dewey if it is a hill or mountain in England or Wales over 500 metres (1640 feet) in altitude, but below 2000 feet (609.6 metres), with a relative height of at least 30 metres (98 feet). The list was originally compiled by Michael Dewey and published in his book Mountain Tables in 1995, hence the name. The list effectively extended the Hewitts (hills over 2000 feet high) down to 500 metres, hence the strange mix of metric and imperial units for the edges of the range.
