    Hi, I'm having trouble calculating the error for my data, essentially the equation is as follow F=x/y where x is in nanometres where y is in millimeters

    atm im using (error of F)^2 = (error on y)^2 +(error on x)^2 I assume this is correct?

    I'm not to sure if i need to leave the units the same or make some sort of common unit, could someone help me out.
    Thanks

    You'll need to convert the errors in each to a common unit. If you choose SI, then make sure to use standard notation.

    The equation should be error of F = error of y + error of x. No squares involved.
