Me thinks...To convert odds to percentage:

1/( <font color="red"> 1.22 </font> +1)= <font color="green"> 45.05% </font>

Just change the number in red each time to fnd the number in green. Pretty easy to do in MS Excel.

Another example, the percentage that a flush will come by the river if you have a flush draw:

1/( <font color="red"> 1.86 </font> +1)= <font color="green"> 34.97% </font>

I am definitely not a strong math person, so I had to noodle this out once...I think it holds up.
