How to use the Sprayer Calibration Calculator

  1. Enter the requested field, crop, animal, equipment, or cost information.
  2. Keep every value in the unit shown beside its field.
  3. Select Calculate and review each result and assumption.
  4. Verify important decisions with local records, labels, extension guidance, or a qualified adviser.

Formula and method

GPA = 5,940 × nozzle flow (GPM) ÷ [speed (mph) × nozzle spacing (in)].

The standard broadcast-sprayer relationship calculates application volume and tank coverage.

Worked example

At 0.3 GPM, 5 mph and 20-inch spacing, output is 17.82 GPA and a 500-gallon tank covers about 28.1 acres.

Understanding the result

Treat the calculated values as a planning estimate. Compare them with your field records, product information, local conditions and operational capacity before acting.

Important: Calibrate with clean water and verify nozzle uniformity, label requirements, PPE and local rules.
