The penny is only one cent because of the way the coin was designed. It's just like asking why 1+1=2 or why is b after a in the alphabet.
Not quite...The use of the term "penny" to refer to one-cent coins in the US and Canada is a slang holdover from the days when each country was a British colony. The British coinage system has had a penny coin for over 1000 years, but there's no formal or legal "penny" in either the US or Canada.
When the US and Canada became independent each decided to use coins based on dollars divided into 100 cents ("cent" is related to words like "percent" and "centennial", all having to do with 100). Early 1-cent coins were made out of copper and were similar in size to British pennies, so people who were accustomed to the old British Coins just kept using the term "penny" for the new 1¢ coins, and the name stuck.
It's a bit like using the expression "dial a telephone" even though most telephones haven't had dials for decades.
