Quick Guide to Use Irrigation Calculator

  • Select Meter Type: Choose the appropriate water flow meter type from the dropdown list.
  • Enter Readings: Input the beginning and ending meter readings, along with the total field in the acres.
  • Calculate: Click the “Calculate” button to generate results.
  • Reset: Use the “Reset” button to clear input fields and start fresh.


Meter Reading in Gallons x 100

Total Water Pumped = Ending Meter Reading – Beginning Meter Reading) x 100/27154

Meter Reading in Gallons x 1000

Total Water Pumped = (Ending Meter Reading – Beginning Meter Reading) x 1000/27154

Meter Reading in Acre-Feet x .001

Total Water Pumped = (Ending Meter Reading – Beginning Meter Reading) x 12/1000

Meter Reading in Acre-Feet x .01

Total Water Pumped = (Ending Meter Reading – Beginning Meter Reading) x 12/100

Meter Reading in Acre-Inches x .01

Total Water Pumped = (Ending Meter Reading – Beginning Meter Reading)/100

Water Applied per Acre =  Total Water Pumped /Field in acres
