Light crude oil on practical grounds than theoretical. The New York Mercantile Exchange (NYMEX) defines light crude oil for domestic U.S. oil as having an API gravity between 37° API (840 kg/m) and 42° API (816 kg/m), while it defines light crude oil for non-U.S. oil as being between 32° API (865 kg/m) and 42° API (816 kg/m). The National Energy Board of Canada defines light crude oil as having a density less than 875.7 kg/m (API gravity greater than 30.1° API). The government of Alberta, which produces most of the oil in Canada, disagrees and defines it as oil with a density
