Using the notation we were taught, 0.0010 plus or minus 0.0001, for example, would be:

(1.0 +/- 0.1)*10^{-3}s

Is there a way to print this in LaTeX using the siunitx package?

    The package siunitx has a good manual that gives you this and also further examples of possible applications. Read first the manual before asking. All latex manuals can be found at www.ctan.org

    @strpeter Almost all the questions asked here have an answer that can be found in the manual of a package. Should we stop asking questions?

%(1.0 +/- 0.1)*10^-3s
\SI[separate-uncertainty = true]{1.0(1)e-3}{\second}


See the manual for the various methods of inputting the uncertainty.

Here is the solution if you want to set this plus-minus notation document-wide:

    Putting it as an optional argument when loading the package works as well: \usepackage[separate-uncertainty=true]{siunitx}.
