Basic math equation help.

In the equation

x = n / f

n is 1 kg m^-2 and f is 1 kg m^-1

What is x?

This is just confusing my poor brain, any help to understand would be much appreciated.

I put what I thought the answer was as x = 1 kg m^2 but I'm told the numerical value is correct but the unit is incorrect, am I being stupid here or am I missing something blatantly obvious?

Thanks for any help regarding this.

[tex]x=\dfrac{n}{f}=\dfrac{1\dfrac{kg}{m^2}}{1\dfrac{kg}{m}}\\
x=1\dfrac{kg}{m^2}\cdot\dfrac{m}{kg}=1m^{-1}[/tex]

This is what x is. One unit per meter.
