How to use Color Temperature ↔ Mired Converter

Enter a value in Kelvin or mired. The tool applies mired = 1,000,000 ÷ K both ways and shows a reference table of common sources.

Frequently asked questions

What is the Kelvin-to-mired formula?

mired = 1,000,000 ÷ Kelvin, and Kelvin = 1,000,000 ÷ mired.

Why use mireds instead of Kelvin?

Mireds add linearly, so lighting gels shift color by a fixed mired amount regardless of the starting temperature.

What is 6500 K in mireds?

6500 K ≈ 153.85 mired, close to daylight/D65, while 3200 K tungsten is 312.5 mired.
