Supports .dxf
Choose fileScales all entities and rewrites the DXF. Supported: LINE/polyline/circle/arc/ellipse/text.
Irreversible scaling notice
All coordinates are globally rescaled (0.001× factor) with floating-point rounding; the original grid precision cannot be fully preserved. The output filename carries the target unit.
What is it? DXF Unit Converter changes the drawing units of a DXF (mm, cm, m, inch, foot) by scaling all entities consistently, so a drawing authored in one unit can be used in another.
TL;DR: Convert DXF between mm/cm/m/inch/ft and rescale all geometry.
How to use
- Open a DXF.
- Select the source and target units.
- Download the rescaled DXF.
FAQ
Is it a lossless conversion?
Yes — coordinates are scaled mathematically; the geometry is unchanged otherwise.
Does it update the DXF header units?
Yes, the $INSUNITS header is rewritten to match the target unit.
Limitations
- Assumes the source drawing already uses the units you select.
- ASCII DXF only.
