✨ unitconv — bestie's lil' energy & length glow-up machine ✨

okay so this is the unitconv page from the XCrySDen manual (section 1, iykyk), and bestie… it's literally just a converter. a simple energy and length units converter, written in Tcl 💅. it's a utility program that ships with the xcrysden package (that's http://www.xcrysden.org/ if you wanna go say hi 🦋).

🌸 NAME 🌸

unitconv — simple energy and length units converter 💖

🎀 SYNOPSIS 🎀

unitconv [unit] value
unitconv [unit] expression

✨ DESCRIPTION ✨

unitconv is a simple energy and length units converter, written in Tcl. no cap. it's a utility program of the xcrysden package (http://www.xcrysden.org/) 🫶

🔥 ENERGY UNITS 🔥

these are the energy units it supports, and the vibe is literally just unit — description pairs, where you drop that unit right onto the command line like it's nothing:

  • au — Hartree 👑
  • ry — Rydberg 🌈
  • ev — eV (electron volt) ⚡
  • kjm — kJ/mol 🍓
  • kj — kJ 💜
  • kcalm — kcal/mol 🧚
  • kcal — kcal 🌸

🦋 LENGTH UNITS 🦋

same energy, same usage as above, just for lengths this time:

  • angs — Angstrom ✨
  • bohr — Bohr radius 💫
  • m — meter 📏

💅 EXAMPLES 💅

convert a value from eV into all the other energy units, slay:

unitconv ev 3.25

calculate an expression (with the values in Rydberg units) and convert it into the other energy units — and bestie, note that the expression must be quoted, like actually, don't forget the quotes 🙈:

unitconv ry "-103.134567 - (-240.691356 - -2*17.543471)/2"

and in your expression you can also use the mathematical functions that are available in tclsh. main character math energy fr fr 🔥
