Field notes

The homepage groups 97 calculators into nine practical sections, ranging from electrical and HVAC to machining, sheet metal, mechanical work, and energy. Its index includes tools such as Conduit Fill, Manual J, Psychrometric, Reynolds Number, Press Brake Tonnage, Beam Deflection, and EV Charging Cost. The page states that calculations run in the browser and that answers are paired with code tables, standards, or definitions compiled from sources including NEC 2023, the IPC, and the ASHRAE Handbook.
