<p>The invention relates to a means for the measurement of longitudinal dimensions, comprising a scale graduated in units corresponding to the measuring unit and provided with means for reading said scale, further a computerized data-acquisition and/or -registering system and a method for measuring and/or computer processing of dimensional data given in technical inches. The scale unit (2) of the scale (1) of the measuring means is a measuring unit equal to 1/16 part of the technical inch and/or its decimal fraction. Expediently, the measuring means is provided with a vernier (3) of a length by one division less than ten, or an integer multiple of ten measuring units, this vernier being graduated in ten, or in some integer multiple of ten, divisions. In another embodiment of the invention the measuring means is provided with a scale graduated in millimeters and with a scale reading means, and with a unit converting the measured value into data expressed in integer measuring units equal to 1/16 part of a technical inch and the decimal fraction of said measuring unit, expressed as a decimal fraction of an accuracy of one or more decimal digits. Its unit for converting the measured values comprises a memory (6) for storing the constant K1 = 1.5875 and a means (8) for dividing the measured values by said constant K1. The computer-backed data-acquisition and/or -registering system incorporates a unit for converting the data entered in technical inches into data expressed in a measuring unit of 1/16 parts of a technical inch and in a decimal fraction of the measuring unit, where a memory for storing the constant K2 = 16 and a means for multiplying by constant K2 the data to be converted is comprised by said converting unit (9). In the measuring method suitable for measuring and/or computer processing of dimensions given in terms of technical inches, the dimension data given in inches will be expressed in an integer of measuring units corresponding to 1/16 of the technical inch and - the rest part of the dimension - in the measuring unit's decimal fraction given in decimal system into the dimension's data, and performing arithmetic and/or storing operations with these quantities.</p> |
