I'm trying to calculate some RGB colors (0 - 255) for a 0 to 1 scale. Does anyone knows a online converter or it exists a math formula?
Lets say that I want to convert 125 RGB with (0 to 255 scale) to a 0 to 1 scale.

A color's RGB value indicates its red, green, and blue intensity. Each intensity value is on a scale of 0 to 255, or in hexadecimal from 00 to FF. RGB values are used in HTML, XHTML, CSS, and other web standards.
It really comes down to math and getting a value between 0-1. Since 255 is the maximum value, dividing by 255 expresses a 0-1 representation. Each channel (Red, Green, and Blue are each channels) is 8 bits, so they are each limited to 256, in this case 255 since 0 is included.
The RGB color 0, 1, 0 is a dark color, and the websafe version is hex 000000.
Black is the zero value at RGB(0,0,0), and White is maximum at RGB(255,255,255).
It's simply a case of dividing your RGB value, call it x by 255:
If x = 95 then your value is 95/255 = 0.373 (to 3 d.p.)
105
a = x / 255 or
x = a * 255 where x is the RGB value and a is your desired result.
