ABSTRACT:
A device for converting between the metric and English systems of measurement including a circular scale disc having concentric scales on one side graduated according to the English system and correlated concentric scales on the opposite sides graduated according to the metric system. A pivoted cursor straddles both sides of the device and has index windows through which related English system and metric system measurements may be read, the scales being correlated so that one index window exhibits an amount according to the English system and the other exhibits a corresponding amount according to the metric system. Certain scales in the metric system have dual functions. A measuring tape is received in a cavity formed in two facing side discs and is moveable endwise in slots formed in the side discs, the tape being marked off according to both the English and the metric system.
