Utility
Grades, passwords, networking and other everyday tools.
The tools that do not belong to a subject — coursework grades, password generation, network addressing, and one that exists purely for fun.
They have little in common beyond being useful to have somewhere, so this page is mostly a signpost.

What these calculators have in common
Assumptions worth knowing before you rely on any result here.
Grading schemes vary by institution
Point values for a given letter, whether plus and minus grades count, and how retakes are treated all differ between schools. Check your own handbook before relying on a GPA figure for an application.
A generated password needs somewhere to live
The whole point of a random password is that you cannot remember it, so it needs a password manager. Generating strong passwords and then storing them in a document or an email draft is worse than a weaker password you actually keep safe.
Nothing you enter here is sent anywhere
Passwords and network details are generated and calculated entirely in your browser. They are never transmitted to us, stored, or logged — which is the only reasonable way to offer a password generator on the web.
