content: A rectangular plastic card fits inside a slot in the base. The card provides various conversion tables for energy, power, the Greek alphabet, velocity, volume, mass, force, length, and area. This side of the card is printed so that the card can be pushed out halfway from either side of the base, and the printed tables will appear right-side-up. The back of the card has tables for gas constant values and pressure, along with lists of mathematical formulas and chemical and physical data. One edge of the card is marked: ©1968 CONCISE INTERNATIONAL CO., LTD. INSERT - ST.
