Detect ppm value from voltage of MQ-6 and MQ-7 sensor

I want to detect a certain range of CO and LP gas but it is in ppm. But the problem i do not know what is the equivalent value since sensor detects in voltage (0-5 V). i need some conversion for it.

for example i need 35ppm of CO, how do i know what is the voltage that is equivalent (between 0-5 V) that is equivalent to 35ppm

Connect the MQ-6 and MQ-7 to an Analog to Digital Converter (ADC) and with the conversion formula on the datasheet you will get the ppm value. Cheers
