# Migrating from SIunits to siunitx: are there any obvious pitfall? [closed]

I understood the differences that were mentioned at the following link. Differences between SIunits and siunitx packages

I am using TexStudio and MikTeX (perhaps the most recent version, considering that I downloaded the whole bundle yesterday) for typesetting my document. After changing all `\unit` to `\SI` I am still getting errors like `line 0 Undefined control sequence`.

How should I get around this problem?

It would be helpful to see a small demo of your `SIunits` input. – Joseph Wright Sep 23 '12 at 18:02
With no concrete demo, this is 'too localized', I'm afraid – Joseph Wright Dec 1 '12 at 22:16
