ABSTRACT:
A small hand held calculator capable of performing the normal arithmetical calculations expected of a calculator of this general type. In addition, the calculator is capable of achieving conversions from any measurement unit to an equivalent value in another selected measurement unit by converting the input measurement unit into a standard unit of measurement and converting that standard unit of measurement into a selected unit of measurement. In addition, any recipe can be converted from a number of servings to any other number of servings and/or a desired portion size can be converted from any given recipe portion size. The data input keyboard comprises a plurality of data input keys with specific indicia thereon including columns of keys for volumes, weights, lengths, recipe servings including the number of servings, portion size, resulting number of servings desired and portion size. The data input keys further include the conventional numbers 0-9 and arithmetical function keys.
