METER
one meter is equal with 1000 milimeters and 4 meters make a square meter so 4000 milimeters make one square meters ++ Sorry but both question and that answer are wrong because they muddle linear with areal measures. Further, 4m does not make a square metre, and though 4m does indeed = 4000mm, 1 square metre = 1 000 000 (million) square millimetres.
You write it as 1m2
