About Jobsite Helpdesk

Free calculators and reference charts built for people who work with their hands.

Why this exists

If you've ever stood on a ladder, in a trench, or under a beam trying to google "pipe weight per foot" while your phone autocorrects every fourth letter, this site is for you. Most of the tools we needed already existed somewhere — buried in a PDF, hidden behind a signup, or wrapped in pop-ups that don't render on a phone in direct sunlight. Jobsite Helpdesk is everything the trades use, in one place, fast.

Who built it

The site is built and maintained by a working tradesman. The calculators are written to match the way trades and engineers actually work — feet and inches, fractions to 1/64, NEC tables, ASME B16.5 flanges, Sch 40 pipe — not academic textbook units.

How we make money

We show ads (Google AdSense) and recommend a few tools through Amazon affiliate links when they're relevant. We don't sell your data, we don't gate calculators behind a paywall, and we don't email you unless you opt in. If you'd like to support the site, the simplest way is to use it and tell a coworker.

What's coming

This is launch v1 with about 25 tools live. The plan is to add 2–3 new calculators or reference charts per month. Got a request? Send it over — most of what's on here started as a "wish I had this" from a real jobsite.

Accuracy and use

Every calculator on this site is double-checked against published references (NEC, ASME, AISC, IRC). That said: do your own verification before pouring concrete, energizing a circuit, or torquing a flange. These tools are decision aids, not engineering stamps.
