title: Units in FreeSewing
order: 40
---

FreeSewing uses _millimeter (mm)_ for all its internal units.
We do support both imperial and metrics units, which are displayed
as _cm_ or _inch_, but under the hood everything is handled in millimeter.

So as a pattern designer, you will work with mm.
When you write `1`, that’s one millimeter. When you write `7.8`, that’s 7.8 mm.

While you can use cm or inch on the FreeSewing website, that is merely a layer of
abstraction on top of the internal units, which are always mm.

-												feat: Flat import of markdown repo

This is a flat (without history) import of (some of) the content
from our markdown module.

We've imported this without history because the repo contains our
blog posts and showcases posts content prior to porting them to strapi.

Since this contains many images, it would balloon the size of this repo
to import the full history.

Instead, please refer to the history of the (archived) markdown repo
at: https://github.com/freesewing/markdown
