convert is an tools of imagemagick ( 
http://www.imagemagick.org/script/convert.php )
The support isn't here.

if you use the Google WebP Tools the command are:

cwebp -q 85 051600005327A60D67379F62450A63E6  -o 
051600005327A60D67379F62450A63E6.webp

I didn't check what the current state is, but this sounds like a bug/feature 
request for imagemagick. You should post a request on their forums [1][2].

it works with ImageMagick 6.8.0-7  at least (the one i have for test)
Just use, for instance: convert in.jpg out.webp

'convert -list format' should give you the list of supported format.
The line with WebP (if supported) looks like:

     WEBP* rw-   WebP Image Format (libwebp 0.3.1)

For the reminder, the WebP encoding options are described here:
