Getting \bm to pass thru siunitx macros

Question

It seems that macros form the \siunitx package have a \bm problem, but no problem with \textcolor:

Note that the 180 passed thru the \ang macro is not bold.

So, how do I change the \MyFormat macro so that \bm passes thru the siunitx macros.

Code:

\documentclass{article}
\usepackage{xcolor}
\usepackage{bm}
\usepackage{siunitx}

\newcommand*{\MyFormat}[2][blue]{\bm{\textcolor{#1}{#2}}}%

\begin{document}

\[ 
    \MyFormat{\frac{180}{\pi}} = \MyFormat{\frac{\ang{180}}{\pi}}
\]

\end{document}

Answer 1

You can configure the siunitx package to detect bold math. Try

\sisetup{detect-weight, detect-display-math}

For in-line formulae, you additionally need:

\sisetup{detect-inline-weight=math}
