So what's the right way to put units inside of TeX blocks? I remember a font directive but not what the word was. And it's a kludge anyway — was a proper unit macro notation ever added?

Use \text{}.
This MathJaX code:
1 \times 10^{23} kg
produces this output:
$ 1 \times 10^{23} kg $
By wrapping the kg in \text{ }, we get:
1 \times 10^{23} \text{ kg}
which produces
$ 1 \times 10^{23} \text{ kg} $

$\begingroup$ So what's the difference between mathrm and text? The latter might have a better chance of being remembered anyway. $\endgroup$ – JDługosz Jan 4 '16 at 5:50

$\begingroup$ @JDługosz the only difference I've found is that mathrm strips spaces, text doesn't. $\endgroup$ – ArtOfCode Jan 4 '16 at 7:46

$\begingroup$ So the tilde on the outside lets $\TeX$ decide the right amount of space, while a space inside of
textforces it to be an actual space character in that font. $\endgroup$ – JDługosz Jan 4 '16 at 12:50 -
1$\begingroup$ You can also use something like
1 \times 10^{23} ~ \text{kg}: $ 1 \times 10^{23} ~ \text{kg} $ $\endgroup$ – user Jan 4 '16 at 15:30
