latitude - One of the two coordinates (the other being longitude) used to locate a position at sea; marked in degrees north or south of the equator, from 0 degrees at the equator to 90 degress north or south at the poles; one degree of latitude = 60 minutes of latitude; as one minute equals a mile, a common saying at sea is "a minute's a mile". Latitude is comparable to the x-axis on a graph.

longitude - One of the two coordinates (the other being latitude) used to locate a position at sea; marked in degrees east or west of the prime meridien (0 degrees longitude) universally accepted to be at Greenwich, England. As there are 360 degrees in a circle, longitude may range up to 180 degrees East or West. 180 degrees East and West, in fact, meet on the other side of the globe from Greenwich, at the International Date Line. Longitude is comparable to the y-axis on a graph.
