How it works
Screens mix red, green and blue light; printers layer cyan, magenta, yellow and black (K, for key) ink. This converter uses the standard simple formula: black is 1 minus the strongest RGB channel, and each ink is what remains of its opposite channel.
Real printing depends on the paper, ink and color profile, so treat these as a starting point. Your printer or design software can give exact values for a specific profile.

Questions
Why do my printed colors look different?
Screens can show brighter colors than ink can print, and each printer, paper and profile changes the result. Ask your printer for a proof if color accuracy matters.
What is K in CMYK?
K stands for key, the black plate. Printers use black ink instead of mixing all three colors to get darker, cleaner blacks.
