The files can also be opened in the open source Inkscape:
Inkscape is professional vector graphics software which runs on Linux, Mac OS X and Windows desktop computers.

If you want to maintain the vector properties (so it can scale without loss of quality), you can convert the SVG to EMF (Enhanced Metafile), which is compatible with Word.
Using Inkscape (Free Software) for Conversion:
- Open the SVG file in Inkscape.
- Go to File > Save As.
- In the Save as type dropdown, choose EMF (Enhanced Metafile).
- Save the file.
- Insert the EMF file into Word:
- Open your Word document.
- Click Insert > Pictures > This Device.
- Select the EMF file to insert it into your document.
