Which Column to Use on the Chart
If you are paying to see the turn, look up the number underneath the "Turn" column.
If you are paying to see the River card, look up the number underneath the "River" column.
If you, or your opponents are going All-In, and you will be calling one bet to see both the Turn and the River, use the column marked "Turn or River".
While that may seem simple, it is too easy to mistakenly think that you'll call a bet for the turn, and then call one for the river, so it would be ok to use the "Turn
or River" column for computing your Pot Odds. That would be a grave mistake.
Once you have:
> The Number of Outs and
> The number from the Chart
you simply multiply the amount of the call by the number in the chart.
Multiplying by numbers like 4.22, or 2.18 isn't something that I do in my head to the second number after the decimal. But, even doing a rough estimate can give often give you enough information to know if you'd be making a terrible call, a questionable call, or a downright solid call.
For Example:
I have a nut flush draw. There is $36 in the pot. I have to call a $6 bet.
The chart says multiply 6 times 4.22. Six time
five is $30, and that's
still less than the $36 pot I'm looking at. My Pot Odds question has been answered, and there was no need to do any kind of math with decimals.
A lot of situations will be just like that.

built in Pot Odds Calculator that will do the math for you. Of course, this is only good for online play, or perhaps reviewing some situations that you find yourself in repeatedly.
