No, that is not a typo. Thos is a typo - an error created during the mechanical act of typing. Yours was just a plain mistake, you got the units wrong. Own it and learn from the error instead of excusing it away.
I didn't see the article before fixes, but I seem to often type "driver" instead of "drive". If one typed "mAh" enough, don't you think a similar thing could happen?
