Re: RGB to CMYK conversion flaw

The thing is, I am working on an iOS app (being an iOS developer) , this app creates SVG of a drawing. Previously it shows RGB colour picker, where we could select R G and B values. After some requirement came and I had to make a CMYK picker, so I get C M Y K input and convert it to RGB (with formula) so that other processes won't be disturbed. So, in this case everything is manual, I myself am doing the conversions. So I think, I have to add the profiles in calculation.

Can you give me reference, how profiles effect color conversions and which profile use which formula for conversion?

There is a situation where I have to transfer colors in Hex Format (from an app) to Adobe Illustrator. But I need to extract the exact CMYK value (that was assigned in the previous app). Long story short. Let's take an example: There is a hex value: #ff7253 it's RGB = rgb(255,114,83) and converted CMYK from RGB (using formulas) : cmyk(0,55,67,0) (conversion link: CMYK to RGB - RGB,CMYK,HEX color codes online converter free ) But If I insert the above RGB or Hex in adobe illustrator color picker: input = rgb(255,114,83) CMYK will be : cmyk(0,69,68,0) and if I insert the CMYK value input : cmyk(0,55,67,0) output : rgb(246,141,94) Kindly tell me how to resolve the issue. How can I get same value for CMYK conversion on Adobe Illustrator ( (RGB>CMYK with formulas) = (RGB>CMYK on illustrator) )? Thanks in advance for your help.
