I think some correction is needed here.

My understanding is that the relationship between mireds (M) and colour temperature (T) is given by the equation:

M=\frac{1000000}{T}

Therefore writing:

"equals 1,000,000 (one million) divided by the reciprocal of a given color temperature" (my emphasis)

as originally appeared in the article is incorrect, as this would imply:

M=\frac{1000000}{1/T}

The first formula above generates the correct mired values, so that for T=10000K, M=100, for T=12000, M=83.3333, and for T=6000, M=166.6667 (to 4 decimal places). The second formula generates incorrect results, and is effectively the same as:

M=1000000 \times T

I am therefore editing this article accordingly. If anyone wishes to give my edit an overview a check, feel free. I also think that a link to this article from the colour temperature article is needed, as photographers will expect this, and the fact that mired and colour temperature are closely related in the world of photography should be present in the latter article.
