Is it just me, or does this cluster of articles define lumen in termas of candela and candela in terms of lumen?—The preceding unsigned comment was added by 206.165.217.125 (talk • contribs) .
- It's just you. "One candela is defined as the luminous intensity of a monochromatic light source of frequency 540 THz...which has a radiant intensity of 1/683 watts per steradian." I'll change "which" to "that" to make it sensible. Dicklyon 22:42, 31 July 2006 (UTC)
Why is this an 'SI base unit' ? Perhaps the article could explain.—The preceding unsigned comment was added by 70.225.166.87 (talk • contribs) 20:11, October 19, 2006.
- The SI base units were chosen to give a complete set of physical quantities that can be precisely measured, so that the definitions of the units are precise. The explanation belongs at SI base unit, and this article does provide a link there.--Srleffler 02:19, 20 October 2006 (UTC)
