Presenting the CalcShed, Universal Calculator

By Giorgi Gaprindashvili 

"Because accuracy cannot rest on my personal say-so, every calculator is built from published industry standards – ASTM and ACI for concrete, the NEC (NFPA 70) for electrical, AASHTO and NRCA references, and manufacturer technical data – and every tool shows the formula and assumptions it uses. You do not have to take my word for anything: you can see the source and the math, and override any default to match your own project, supplier, or local code."
