When working with design specs or technical documents, I often run into measurements written in millimeters.
On paper, converting millimeters to centimeters is simple:
1 cm = 10 mm.
So you just divide by 10.
However, in real work scenarios—especially when dealing with multiple values—it’s surprisingly easy to make mistakes or slow yourself down.
I’ve seen this happen when:
Checking design specs
Working with PDFs or print layouts
Reading hardware documentation
Sure, you can calculate it manually every time, but that quickly becomes annoying.
For this reason, I usually rely on a small online converter to handle these quick checks. One I often use is mmtocm.net, because it’s lightweight, fast, and doesn’t require any login.
It’s not a complex tool, but it removes friction from a very common task.
Sometimes, small utilities like this save more time than big frameworks.
