General Calculations

Notes: "This is a standard Mannheim slide rule, and both the D&P mark and the patent number in the well. The front face has the usual A, B, C, and D scales, and the back of the slide has S, L, and T scales. The centimeter ruler on the upper, beveled edge is divided into millimeters, and the inch ruler on the lower vertical edge is divided into 10ths of an inch, rather than the more common 8ths or 16ths.
