arduino - How to calculate Gas sensor PPM from analog ...

I am new to Arduino and electronics in am working on MQ 7 Gas sensor to test Carbon monoxide level. But the issue is i still can't grasp the concept of converting analog readings to PPM. I tried to follow this,but some parts, are very clear especially R0 = RS_air/(26+(1/3)) So far with my code below the ratio I get is between 20 and 30.

MQ 2 Gas Sensor - IoCT

In order to connect the MQ 2 sensor to the Raspberry Pi, two other sensors are needed. A level converter is needed to take the 5V output signal to a signal and an A/D converter to be able to read the signal in digital form. It is necessary to step the voltage down because a raspberry pi can only read signals at without potential for damage. The A/D converter changes the analog signal ...
