I kept Googling "sqm to sqft" so I built a tiny free converter instead
While working on a larger unit conversion project, I noticed something interesting.
I wasn't searching for complicated conversions. I kept searching for very basic ones.
- sqm to sqft
- hectares to square meters
- square feet to acres
- Celsius to Fahrenheit
Every time I landed on a different website.
Some were filled with ads.
Some hid the answer below a long article.
Others weren't mobile-friendly or made simple conversions feel unnecessarily complicated.
So I decided to build a simple solution.
The goal wasn't to build another "AI-powered" tool or the next SaaS.
The goal was simply:
Enter a value. Get the correct answer instantly.
No login.
No pop-ups.
No unnecessary steps.
One of the first tools I finished was the Sqm to Sqft Converter:
https://unitmorph.com/sqm-to-sqft-converter/
Building the converter itself took very little time.
The bigger challenge has actually been everything around it:
- making calculations accurate
- creating pages that are genuinely useful instead of thin SEO content
- improving page speed
- making the interface work well on mobile
- organizing hundreds of future converters without creating maintenance headaches
It's one of those projects where the "simple" product ends up having lots of small engineering and UX decisions behind it.
I'm also trying something different with content.
Instead of creating generic pages, every converter gets:
- clear formulas
- worked examples
- conversion tables
- explanations for beginners
- practical use cases
The hope is that someone searching for a quick conversion can also understand why the conversion works.
If anyone is curious, the rest of the project lives here:
I'd love to hear from other builders who have worked on utility websites or SEO-driven products.
Question: What's been the hardest part for you: getting traffic, improving UX, or deciding which tools/features to build next?
