like wisc said, the 0-0-60 means the % of potassium your plants can use. So just for fun lets say you have soil sampled and they recommend you apply 80 pounds of actual potassium per acre. If you applied 80 pounds of 0-0-60 per acre you would only be applying 48 pounds of actual potassium so you would have a shortage. Instead you take 80/.6 which comes out to 133.3 pounds. So if you apply 133.3 pounds of 0-0-60 per acre you are applying 80 pounds of actual potassium. (obviously you don't have to set your machine right to the decimal point, I would just round up to 135 pounds per acre for easier figuring) Hope this helps!
You forgot to convert k20 to elemental k.
Potash is 60# of K20 or 50# of K.
To apply 80# of K it will take 160# of potash.
So 100# of potash is 50# of K.
