Conversion Factors for Water Quality

Enter a concentration, mg/l as Total P, then depress calculate button.
Enter Concentration as Total P :


Resultant concentration as TPO4:

 

Convert Total PO4 to Total P
Note: Total PO4 (mg/l as PO4) x 0.3262 = Total P
At wt of P=30.97; of O=15.99
[TPO4] = [TP] (94.93/30.97)

Miscellaneous Water Quality Calculations and Conversions
Temperature Conversion
note: equivalent change change in C x 1.8 = change in F

Enter a number in either temperature field, then click outside it's box.
 

Temperature in degree F:
Temperature in degree C:

 

Convert Total P to Total PO4
Note: Total P (mg/l as P) x 3.065 = Total PO4
At wt of P=30.97; of O=15.99
[TPO4] = [TP] (94.93/30.97)
 

Enter a concentration, mg/l as Total P, then depress calculate button.
Enter Concentration as Total P :


Resultant concentration as TPO4:

 

Convert Total PO4 to Total P
Note: Total PO4 (mg/l as PO4) x 0.3262 = Total P
At wt of P=30.97; of O=15.99
[TPO4] = [TP] (94.93/30.97)
 

Enter a concentration, mg/l as Total PO4, then depress calculate button.
Enter Concentration as Total PO4 :


Resultant concentration as TP:


Calculate Loading Based on Stream Flow (cubic feet per sec)
Note: mg/l x ft3/s x 2.446 = kg/day; kg/day x 2.205 = lbs/day;
2,000 lbs = one ton
 

Enter a concentration, in mg/l and river flow, in cfs, then depress calculate button(s).
Enter Parameter Concentration:
Enter Flow:


Resultant Loading in kg/day:


Resultant Loading in lbs/day:
