Units & conversions
Keep millimetres, metres and square metres adding up correctly.
What this is for
Sign OS converts between the units you buy in and the units you quote in — millimetres to square metres, rolls to lineal metres. Units and conversions are what make that maths correct behind the scenes.

Step by step

Open Settings → Units & conversions from the sidebar.

Review the units already set up and their Factor to base — that factor is how each unit converts.
- 3
Under Add custom unit, fill in the Type, Name, Abbreviation and Factor to base, then click Add unit if you work in a unit that is not covered. System units are locked.
- 4
Your recipes and quotes now convert sizes correctly.
Tips & gotchas
- Most shops never touch this after setup — it just works. Come here only if a size looks wrong in a quote.
