    I feel so stupid for asking this! I'm blaming it on my tiredness at this time of the morning...

    I just can't seem to work this out. Okay, so I need to find L^2 in meters. L is 400mm.

    L = 0.4m, which squared is 0.16m.

    L = 400mm, which squared is 160000mm = 160m NOT 0.16m!


    Which is correct?! I feel very ashamed of myself right now haha. You know where you're so tired you can't remember how to spell the most basic words? I appear to feeling this with maths. Thanks for the help

    Your problem is that your unit is m^2, not m. There's 1,000,000 mm^2 in a m^2.

    Edit- to make it more clear L^2= 0.16m^2, L^2=160000mm^2=0.16m^2.

    It's because you've confused the units.

    L=0.4m
    L^2 = 0.16m^2

    L=400mm
    L^2 = 160000mm^2

    1000mm = 1m

    So

    1000^2mm^2 = 1^2 m^2

    Thank you I see now, and feel even more ashamed haha.

    Well it's not 2+2, but I'm doing a module in Engineering Mathematics for my degree, so I really should know this

    It's pretty easy you think about what a metre and a metre squared actually are.

    1 square metre = 1 metre x 1 metre

    1 metre = 1000 mm

    so 1 square metre = 1000mm x 1000mm = 1 000 000mm
