Convert Phosphorus PPB to PPM and Phosphate

 
 
Hanna Phosphorus HC colorimeter
 
 
  I wrote this as I was always forgeting how to convert Hanna Phosphorus ULR (HI-736) PPB measures to Phosphate ppm, of course its a simple "ppm = ppb * 3.0661 /1000". Anyway this is easy for me! simply put in your PPB and it will spit out some PPM. I hope its useful to someone.

  The output colours are based on a max of 0.07ppm and min 0.03ppm being safe, anything outside those numbers is classed as not ideal, above 0.07 then please look into why your numbers are high and consider a water change, below 0.03 then consider, are your inhabitants getting enough phosphate?
