i finally got my phosphate checker

i bought the phosphorus checker cuz it measures lower
it measures ppb does someone no the conversion to ppm
im getting a reading of 30ppb but i understand ppm better

thanks

0.030 ppm. Just move the decimal 3 places to the left to convert from ppb to ppm.

i just did a google search and it said to divide by 1000


thanks

30ppb x 3.066 = 91.98 then divide by 1000 = .09198 ppm

30ppb x 3.066 = 91.98 then divide by 1000 = .09198 ppm

huh?????:squigglemouth:

ppb is parts per billion
ppm is parts per million.

so why the 3.066?

 

[zoeyo5]

the low range measures phosphorus and to get phosphate you multiply it by 3.066 and that gives you phosphates in parts per billion then divide by 1000 to get parts per million

Awwwwww
