Say below simple example:

\documentclass[border=1mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,arrows}
\begin{document}
\begin{tikzpicture}
  \draw [-{Stealth[length=3mm, width=2mm]}] (0,0.5) -- (3mm,0.5);
\end{tikzpicture}
\end{document}

What's the line width (default value is 1) in mm should be?

The default line width is 0.4pt. 1pt is 1/72.27in. 1in is 25.4mm. (What are the various units (ex, em, in, pt, bp, dd, pc) expressed in mm?).

So the default line width in TikZ is 0.14mm.
