About HexConvert and Numeros.pro

In their own words, as submitted to SaaSHub.

HexConvert
Numeros.pro

Registers, masks, floats, and checksums — plus base conversion with arbitrary precision. Every integer path runs on BigInt, never a float, so 64 and 128-bit values stay exact to the last digit. Instant, in-browser. Nothing uploaded. No ads.

Questions & Answers

As answered by people managing HexConvert and Numeros.pro.

What makes your product unique?

Numeros.pro's answer:

Transparency. Every calculator shows the exact formula it uses, works through a real example, and states plainly what the result cannot tell you. Formulas come from published sources (Mifflin-St Jeor, Regulation Z, ACI 308R) — not copied from other sites — and every tool is tested at the boundaries where calculators usually break. On top of that: no sign-up, no limits, and 100% privacy — every calculation runs entirely in your browser.

Why should a person choose your product over its competitors?

Numeros.pro's answer:

Because a number you cannot check is a number you should not act on. Most online calculators are black boxes — you get a result but no way to verify it. Numeros shows its working: the equation, a worked example, and its honest limits, so you can trust or challenge every figure. And it is completely free — no accounts, no email walls, no premium tier.

How would you describe the primary audience of your product?

Numeros.pro's answer:

Everyday people who need quick, trustworthy answers: someone checking a loan payment, counting working days across holidays, estimating their BMR, or planning concrete curing time. Students, engineers, DIY builders, and small-business owners — mostly arriving from Google search, mostly on mobile, and all of them wanting the number AND the reasoning behind it.

What's the story behind your product?

Numeros.pro's answer:

It started with a frustrating discovery: when you check the leading calculators for the same question, they often agree with each other — and are all wrong in the same way (reporting months as fixed 30.44-day blocks, ignoring public holidays, using outdated formulas). Numeros was built as the opposite approach: take every formula from the paper or standard that defined it, verify against hand-computed references, test the edge cases, and publish the limits honestly. That deliberate slowness is why there are 400+ tools rather than 4,000.

Which are the primary technologies used for building your product?

Numeros.pro's answer:

Custom HTML5, CSS and vanilla JavaScript — every calculation runs client-side in the user's browser, with no backend, no databases and no tracking. The site is served on Google's infrastructure.

Who are some of the biggest customers of your product?

Numeros.pro's answer:

  • None — Numeros is a free tool for individual users, with no accounts or business clients
  • Our "customers" are everyday people worldwide: students, engineers, builders, and anyone searching Google for a quick, verifiable calculation
