   Oh that looks like it accidentally ended up in an indent/code block, fix being deindent by a little:

   matplotlib/lib/matplotlib/quiver.py

   Lines 144 to 148 in 726af38

   	The rendered arrow length is given by
   	length in x direction = $\\frac{u}{\\mathrm{scale}} \\mathrm{scale_unit}$
   	length in y direction = $\\frac{v}{\\mathrm{scale}} \\mathrm{scale_unit}$

   
   Seperatly, I'd also add bullets.

   @amishamehta99 go for it! The annoying part here is please just check your rendered docs fix the issue before marking your PR as ready to review. (Which you likely were already planning to do).

   Hi @FrimpsManu, I had started looking into this after @story645 suggested I go ahead. I'll open a PR shortly.

   I couldn't respond earlier to confirm, so I just wanted to mention that I had already begun working on it.

    Hi @story645,

    I opened PR #31252 to address this issue and have updated the rendering based on the earlier feedback. I verified the documentation through the CI-built docs, and it now shows:

    length in x direction = (u / scale) * scale_units
    length in y direction = (v / scale) * scale_units

    Before making any further changes, I just wanted to confirm whether this is the expected rendered format according to this issue.
    If anything still needs adjustment, I’d be happy to update it. Thank you!
