I'm having some problems when try align numbers, results from calculations, using siunitx package. That is my code.

documentclass{article}

usepackage{siunitx}

usepackage{fp}

usepackage{booktabs}



% #1: decimal places (default=2), #2: value

newcommand*{KelvinToCelsius}[2][2]{%

    FPevaltempKtoC{round((#2-273.15):#1)}%

    num{tempKtoC}%

}



begin{document}

    begin{tabular}{S S}

        toprule

        si{kelvin} & si{celsius} \

        midrule

           10.3  & {KelvinToCelsius{10.3}}     \

          200.34 & {KelvinToCelsius{200.34}}   \

          500.26 & {KelvinToCelsius{500.26}}   \

         1200.5  & {KelvinToCelsius[1]{1200.5}}\

        12345    & {KelvinToCelsius[0]{12345}} \

        bottomrule

    end{tabular}

end{document}

Which produces:

Note that the numbers in second column don't be align.

How to solve this?

  Maybe section 7.2 "Expanding content in tables" of the siunitx manual can help you.

  You need something expandable, use the xfp package instead of fp and avoid optional arguments.
