I have a Abbreviation page in my PDF. For aligning all the '-' I am using align*.
All the content inside align shows up in italics.
How do I make the content inside align appear normal and not italic?
A simple approach would be to duplicate the contents of the widest entry (either left or right) on the opposite side, accommodating for some overlap:
\documentclass{article}
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\usepackage{amsmath}% http://ctan.org/pkg/amsmath
\begin{document}
\lipsum[2]
\begin{align*}
-3z &= -9 \\
z &= 3 \\
-3y-3*3 &= 3 \\
y &= -4 \\
2x+8*(-4)+4*3 &= 2 \\
x &= 11
\end{align*}
\lipsum[2]
\begin{align*}
-3z &= -9 \\
z &= 3 \\
-3y-3*3 &= 3 \\
y &= -4 \\
2x+8*(-4)+4*3 &= \rlap{2}\phantom{2x+8*(-4)+4*3} \\
x &= 11
\end{align*}
\lipsum[2]
\end{document}
Alternatively, if you're not concerned about numbering the equations, then you can use the following construction:
\documentclass{article}
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\usepackage{amsmath}% http://ctan.org/pkg/amsmath
\usepackage{array}% http://ctan.org/pkg/array
\newsavebox{\mymathbox}
\newcolumntype{R}{>{\begin{lrbox}{\mymathbox}$}r<{$\end{lrbox}\llap{\usebox{\mymathbox}}}}%
\newcolumntype{L}{>{\begin{lrbox}{\mymathbox}$}l<{$\end{lrbox}\rlap{\usebox{\mymathbox}}}}%
\begin{document}
\lipsum[2]
\begin{align*}
-3z &= -9 \\
z &= 3 \\
-3y-3*3 &= 3 \\
y &= -4 \\
2x+8*(-4)+4*3 &= 2 \\
x &= 11
\end{align*}
\lipsum[2]
\[
\renewcommand{\arraystretch}{1.2}
\begin{array}{R@{{}={}}L}
-3z & -9 \\
z & 3 \\
-3y-3*3 & 3 \\
y & -4 \\
2x+8*(-4)+4*3 & 2 \\
x & 11
\end{array} \]
\lipsum[2]
\end{document}
This constructs an align* in the form of an array and places the contents on either side of the equal sign in a zero-width box. Consequently, then equations seem centred based on =.
Note that \rlap and \llap uses \makebox, which inserts its contents in text mode. Hence the switch back to math mode via $ in the automated construction of the L and R column types.
Simply use \sisetup{detect-all = true}
See the documentation on page 20:
The siunitx package controls the font used to print output independently of the surrounding material. The standard method is to ignore the surroundings entirely, and to use the current body fonts. However, the package can detect and follow surrounding bold, italic and font family changes.
\documentclass{article}
\usepackage{siunitx}
\begin{document}
\SI{7}{\metre}
%Change to detect-all = true
\sisetup{detect-all = true}
\textit{\SI{7}{\metre}}
%Change it back to detect-none = true
\sisetup{detect-none = true}
\textit{\SI{7}{\metre}}
\end{document}
The documentation also says on page 83:
The mathematical meaning of units also means that the shape, weight and family are important. Units are supposed to be typeset in an upright, medium weight serif font. Italic, bold and sans serif are all used mathematically to convey other meanings.
Maybe you should think over using italic units

Environment
align(*)is a math-related environment. You should use atabularenvironment: with the header as below, you will probably get what you want.If your list becomes longer than one page, consider using package
longtableor similar.
