Engineering Calculations in Excel

Every engineer uses Excel, and few of them build a sheet anyone could sign. The difference is not knowing the functions. It is that the sheet shows where every number came from, exposes its own errors, and still makes sense two years later in somebody else's hands. This guide is about that difference. A calculation sheet another engineer can check: its layout and the separation of inputs from calculation, a units column and named ranges, the core functions and rounding, lookup tables with linear and bilinear interpolation, iterative solution by goal seek, self-checks and cell protection, presentation and printing to A4, then review and version control. 10 fully worked examples, every number checked. To Microsoft Excel · official function documentation, IEEE 754, FAST Standard · spreadsheet modelling practice. 32 pages · Level EL 100 · Revision A. Whoever owns revision A receives every later revision free.
