OhmNexus is an electrical engineering authority in progress: a platform of calculators, design tools, guides, and (eventually) professional engineering design services, organized around roughly 26 categories that map to real electrical engineering disciplines rather than a random grab-bag of tools.
What's live today covers unit conversions, wire/cable sizing, and battery calculators, all engineered to the actual standard (NEC/NFPA 70, IEC, IEEE) instead of a generic formula, with the underlying math shown on the page. That's the foundation, not the ceiling. The site is early in its build-out and is expanding category by category toward comprehensive coverage across the electrical engineering field, from beginner conversions to advanced design references.
No account required to use any calculator.

OhmNexus's answer:
It's built as a full electrical engineering authority, not a single-purpose calculator. Today that means conversions, wire/cable sizing, and battery calculators built to the actual standard (NEC/NFPA 70, IEC, IEEE) instead of a generic formula, with the math shown on the page rather than hidden. That's the early stage. The site is organized around roughly 26 categories mapping to real electrical engineering disciplines, and the roadmap runs into advanced design tools, in-depth guides, and eventually engineering design services, all built on the same standards-based approach from day one, working toward being a single reference point for the field rather than a scattered set of tools.
OhmNexus's answer:
Most sites in this space are a grab-bag of unrelated calculators bolted together. OhmNexus is being built discipline by discipline, roughly 26 categories that map to real electrical engineering fields, so coverage in any one area is deep and consistent instead of scattered. Every tool checks against the actual standard (NEC/IEC/AS-NZS) instead of a shortcut formula, and the math is shown, not hidden. That same foundation carries forward as the site grows from calculators into design tools, guides, and engineering services.
OhmNexus's answer:
Today: electricians and contractors doing load calcs and wire sizing in the field, electrical/electronics engineering students checking work against real standards, and makers/DIYers on solar, RV, and battery projects. As the platform fills out across its 26 disciplines with design tools and reference guides, that widens to practicing engineers and designers who need standards-checked numbers without opening a full design suite, plus anyone evaluating engineering design services down the line.
OhmNexus's answer:
A modern static-site architecture built for speed, with hand-built calculation logic per tool rather than a shared, generic math library, and standard cloud CDN hosting for global performance.
OhmNexus's answer:
Electrical calculator sites online are almost all the same handful of unit converters repeated with different branding, none of them organized by discipline and none of them showing their formulas. OhmNexus started as an attempt to build the reference the field is actually missing: tools grouped by real electrical engineering categories, calculated to the actual standard instead of a shortcut, with the math visible on the page. It launched with the conversion and load-calculation basics built to that standard, and is being filled in from there toward guides, design tools, and eventually engineering design services.
