I built https://170cminfeet.com — a minimal site that does one thing: convert height from centimeters to feet and inches.
This idea came out of my research into what kinds of things people Google every day. One surprisingly high-volume query was "170 cm in feet". That made me think: maybe there's value in creating a dead-simple, fast, and mobile-friendly page just for that.
What it does:
- Instantly converts common heights like 160cm, 170cm, 175cm etc. into feet/inches
- Automatically shows the result on page load for the target value
- SEO-optimized so that it ranks for those long-tail "xxx cm in feet" searches
- Lightweight (vanilla HTML/CSS/JS, no frameworks, < 10KB total)
Why I made it:
- Experiment with building SEO micro-sites that target very specific user intents
- Learn more about Cloudflare R2 for image hosting + caching
- Test how fast I can go from idea → live project (this took < 2 days)
I'm currently generating other versions like:
- 160cminfeet.com
- 180cminfeet.com
- and also multi-language versions (Korean, Japanese, etc.)
Would love your feedback on:
- Page speed / UX
- SEO structure (meta / canonical / internal linking)
- Any fun ideas for automating or scaling this kind of content
The code is super simple — if anyone’s curious, I can open source it too.
Thanks!
