The decare (/ˈdɛkɑːr/ or /ˈdɛkɛər/) is derived from deca and are, and is equal to 10 ares or 1000 square metres. It is used in Norway and in the former Ottoman areas of the Middle East and the Balkans (Bulgaria) as a measure of land area. Instead of the name "decare", the names of traditional land measures are usually used, redefined as one decare:
