support \SI and \si from siunitx

@samridhgupta is \per any different from /?

[kevinbarabash]

Apparently it does. From the docs for the siunitx package:

\si[per-mode=symbol]
{\kilogram\metre\per\ampere\per\second}

results in

kg m/(A s)

[krtko1]

is there any progress?

[kevinbarabash]

None yet. This is tricky because the non-optional argument to \si requires custom parsing in order for \per\ampere\per\second to be combined into /(A s).

I'm curious about the benefits of this package. It seems like it'd be easier to type:

\text{kg\,m/(A\,s)}

than

\si[per-mode=symbol]{\kilogram\metre\per\ampere\per\second}

The benefit of this package is that you can obtain unified style of units across the pages, the spacing is always determined automatically, and the document becomes more semantic.
Also it allows to write something like \SI{2.04e6}{\metre\per\second} , which renders like $ 2.04 \times 10^6 \text{m \, s}^{^1} $

I do want this function available for KaTeX too.

Any progress on this feature? It would be really nice if KaTeX could support siunitx, even if it is only rudimentarily .

[krtko1]

100% agree, but no progress was made, I think.

I would also like proper parsing... Currently, I use the following workaround:

var macros = {
  "\\SI": "{#1\\;\\mathrm{#2}}",
  "\\squared": "{^{2}}",
  "\\cubed": "{^{3}}",
  "\\per": "/",
  "\\tera": "T",
  "\\giga": "G",
  "\\mega": "M",
  "\\kilo": "k",
  "\\milli": "m",
  "\\micro": "μ",
  "\\nano": "n",
  "\\kilogram": "\\text{kg}\\,",
  "\\meter": "\\text{m}\\,",
  "\\second": "\\text{s}\\,",
  "\\ampere": "\\text{A}\\,",
  "\\kelvin": "\\text{K}\\,",
  "\\mol": "\\text{mol}\\,",
  "\\candela": "\\text{cd}\\,",
  "\\newton": "\\text{N}\\,",
  "\\hertz": "\\text{Hz}\\,",
  "\\pascal": "\\text{Pa}\\,",
  "\\volt": "\\text{V}\\,",
  "\\watt": "\\text{W}\\,",
  "\\joule": "\\text{J}\\,",
  "\\henry": "\\text{H}\\,",
  "\\farad": "\\text{F}\\,",
  "\\coulomb": "\\text{C}\\,",
  "\\ohm": "\\Omega\\,",
  "\\weber": "\\text{Wb}\\,",
  "\\tesla": "\\text{T}\\,",
  "\\degree": "\\text{deg}\\,"
};

...

katex.render(el.innerHTML, el, { displayMode: true, macros: macros })

[karlkappe]

Are there any new?

[myzinsky]

That feature would be important for us
