ABSTRACT:
The measuring tape includes a measuring scale on both sides of the metal tape. The upper surface of the tape is scaled from zero to a number equal to the length of the tape, and the underside of the tape is scaled from the length of the tape of a measurement equal to twice the length of the tape. Thus, the tape can be used to measure a distance equal to twice its length.
