Questions & Answers

As answered by people managing CalcFormula and Comapi.

What makes your product unique?

CalcFormula's answer

Most free calculator sites either cover one narrow topic or stretch across hundreds of unrelated categories with shallow content. CalcFormula stays focused on construction and electrical work specifically, and every formula is checked against real sources — ACI, IBC/IRC, ASTM, ASME — rather than copied from other calculator sites. Several tools also go further than typical competitors: multiple shape options, flexible unit entry (enter any two known dimensions instead of one fixed set), and reverse-solve modes that let you work backward from a known result.

How would you describe the primary audience of your product?

CalcFormula's answer

Contractors, tradespeople, and DIY homeowners working on construction and electrical projects — anyone who needs a quick, accurate calculation for concrete, framing, roofing, drainage, steel weight, pipe sizing, or electrical load and cable sizing, without digging through a textbook or code manual first.

Why should a person choose your product over its competitors?

CalcFormula's answer

Accuracy and scope, mainly. A lot of competing calculators use rounded shortcut formulas instead of exact ones, or only handle the single most common input case. CalcFormula's tools are verified against code and engineering sources, cover more real-world variations (shapes, entry modes, unit systems), and are completely free with no signup — you land on the tool and get an answer immediately.

What's the story behind your product?

CalcFormula's answer

CalcFormula started as a single construction calculator about four months ago and grew from there. The biggest lesson along the way: the tool's actual scope mattered more than expected. A page would underperform and it was easy to assume the writing was thin, but the real problem was often that the calculator only handled one shape or one input method when comparable tools handled three or four. Fixing the tool itself made more difference than any amount of rewriting the page around it.

Which are the primary technologies used for building your product?

CalcFormula's answer

WordPress, with custom HTML/CSS/JavaScript calculator tools built directly into each page.
