Hey everyone 👋
So I recently found myself doing a bunch of annoying math converting hours and minutes into decimal format. You know, like when you’re filling out a timesheet or invoicing someone and need to turn 2 hours 45 minutes into 2.75?
It’s not hard math, but it’s just... annoying. Especially when you’re doing it multiple times a day.
So I made a quick little site:
👉 https://www.timetodecimalcalculator.com
Why I made it
Honestly? Because I was tired of Googling "2 hours 45 minutes to decimal" and clicking on spammy sites with ads everywhere. Most of the tools I found either looked like they were made in 2003 or tried to do way too much.
I just wanted something clean, simple, and fast. So I built one myself.
What it does
It’s super straightforward:
You enter the hours and minutes
It shows the decimal version instantly
That’s it 😄
No popups, no distractions, no waiting. Just one job, done well.
Tech stack (nothing fancy)
I kept it really simple:
Nextjs, TailwindCSS
Hosted on Vercel
Loads fast, works on mobile, does its job
No frameworks, no backend — just a quick and functional tool.
A few things I learned
Even with a tiny project like this, I learned a lot:
Simple can be powerful — People appreciate tools that don’t waste their time.
Mobile-first matters — A lot of people use these kinds of tools on their phone.
Build it for yourself first — If it solves your own problem, odds are it’ll help someone else too.
What’s next?
Not sure yet! Maybe I’ll add:
A reverse calculator (decimal to HH:MM)
A "copy to clipboard" button
A little Chrome extension version?
Open to ideas if you’ve got any!
Check it out
Anyway, if you ever need to do quick time-to-decimal conversions (or know someone who does), feel free to try it out:

Let me know what you think — I’d love feedback, feature requests, or just a “hey this is neat” 😊
Thanks for reading!
