Why on earth would you want to put ls in backticks?  I wonder who
originated this rather redundant and fragile (what happens when a
filename has any form of whitespace?) construct?  Try googling for
"useless use of cat awards" for another redundant construct that
people love to use.

for f in *.bmp ; do convert $f --to-jpeg ; done


But even better than the above is just:
mogrify -format jpg *.bmp
You can probably also (untested):
convert --to-jpeg *.bmp
