Pipe inspection, specifically in-line inspection (ILI) validation work, requires an understanding of how to locate and mark a part with the area where the tool data indicates an anomaly. In direct assessment of an anomaly, the location of what is found must also be determined and reported.

Depending on the ILI tool type and vendor, the circumferential location of a call may be given in a clock position or degrees and may need to be converted. This presentation will explain the basis for conversion between clock, degrees, and physical measurement, and how Microsoft Excel® quantifies clock as a value, which is then used to formulate the desired conversions.
