My university requires double spacing within paragraphs and triple spacing between paragraphs. It also requires triple spacing before each section heading and after the chapter title. I used:
\documentclass [12pt, a4paper, twoside, openany]{report}
...
%Triple spacing between paragraphs
\setlength\parskip{36pt}
%For double spacing, add \doublespacing after \begin{document}
\usepackage[nodisplayskipstretch]{setspace}
...
%For centering of chapter titles:
\usepackage{titlesec}
\titleformat{\chapter}[display]
{\normalfont\huge\bfseries\centering}{\chaptertitlename\ \thechapter}{1em}{\Huge}
%Change Section Headings and lower headings' font size to 12pt
\titleformat{\section}
{\normalfont\normalsize\bfseries}{\thesection}{1em}{}
\titleformat{\subsection}
{\normalfont\normalsize\bfseries}{\thesubsection}{1em}{}
\titleformat{\subsubsection}
{\normalfont\normalsize\bfseries}{\thesubsubsection}{1em}{}
%Change spacing between chapter titles and text
\titlespacing*{\chapter}{0pt}{0pt}{27pt}
%Change spacing between section titles and text
\titlespacing*{\section}{0pt}{36pt}{24pt}
\titlespacing*{\subsection}{0pt}{36pt}{24pt}
\titlespacing*{\subsubsection}{0pt}{36pt}{24pt}
Here is the output:

I'm confused as to what is the definition of line spacing for the document class report with a 12pt normal font. Linespread and baselineskip only add to the confusion.
From what I gathered from the internet, double spacing isn't 24 pt if the normal font is 12 pt. Also, the skip or space between lines and paragraphs is also computed differently. Please help me resolve this confusion. Thank you.
P.S. How do we remove all that unnecessary space between "Chapter #" and "Chapter Title"?
