Kelvin to mireds
Type a value in K to get it in MK⁻¹ instantly.
That's about the same as midday daylight. That is cool light: daylight and the blue-white of an overcast sky.
Convert the other way: MK⁻¹ to K
What it means
What color is that light?
Color temperature strictly describes a glowing black body. LEDs and fluorescents get a "correlated" temperature: the nearest match, not a real one.
The math
How to convert K to MK⁻¹
Mireds are the reciprocal of kelvin: mireds = 1,000,000 ÷ K, and back again K = 1,000,000 ÷ mireds. Peak wavelength comes from Wien’s law, λ = 2,897,772 ÷ K nanometers.
Example: 5,500 K = 181.818 MK⁻¹.

About these units
Kelvin (K)
The standard scale: the temperature a glowing body would need to look this color.
Mireds (MK⁻¹)
A million divided by kelvin. Equal steps in mireds are equal visible shifts.
