Abstract: A measurement device including a generally flat member having a first edge extending therealong, a first set of British scale graduations formed along the first edge and extending inwardly of the first edge for a desired distance, and a first set of metric scale graduations formed adjacent the first set of British scale graduations and spaced in parallel relationship from the first edge of the generally flat member by approximately the length of the desired distance that the first set of British scale graduations extends inwardly. The first set of British scale graduations has numerical designations arranged in a first orientation. The first set of metric scale graduations has numerical designations arranged in a similar orientation as the numerical designations of the first set of British scale graduations.
