The problem I kept running into

Every time I needed to convert units — inches to centimeters, pounds to kilograms, Celsius to Fahrenheit — I ended up on a slow, ad-filled website.

Pop-ups. Banner ads. "Please sign up for free." "Upgrade to pro for 5 more conversions."

I just wanted to convert 10 miles to kilometers. Not create an account.

So I built my own

I created EveryUnitConverter.com — a unit converter that does exactly one thing and does it well.

What it offers:

350+ unit types across 47 categories

Length, weight, temperature, volume, cooking, area, speed, time, and more

Instant results as you type

No ads, no pop-ups, no distractions

No signup, no email, no tracking

Works on desktop and mobile

Why I kept it free

I built this tool for myself first. Then I realized other people probably have the same frustration.

So I decided to keep it completely free. Forever.

No "freemium" tier. No ads. No data collection.…
