Calculation ppm's of a liquid fertilizer 

I have a Liquid iron fertilizer that has 6.1% iron.
I have a fertilizer injector that is 1:125 (which means that it is 1 part fertilizer to 125 parts water)
My first question: If I inject the liquid iron without any dilution then how do I calculate the ppm's of iron?
My second question: If I dilute the liquid iron with water (let's say 1 gallon fertilizer into 100 gallons water) then how would I calculate the ppm's of iron

Re: Calculation ppm's of a liquid fertilizer 

If your injector uses a 1:125 then and the fertilzer has 6.1% iron then the mathimatical way is simply 125/6.1 or.0488% iron per gallon of water.I'm not a math wizard so you may want to check my calculation but I believe this is correct.
