| Item | Value / formula |
|---|---|
| 1 acre | 43,560 sq ft |
| 1 gallon | 128 fl oz = 4 qt = 8 pt |
| Acres per tank | tank gallons ÷ gallons per acre |
| Product per tank | rate per acre × acres per tank |
| Product for a % a.i. rate | lb a.i. needed ÷ (percent a.i. ÷ 100) |
| Speed (mph) | feet per minute ÷ 88 |
| Broadcast GPA | (GPM × 5,940) ÷ (mph × nozzle spacing in inches) |
| 1/128-acre method | fl oz caught = gallons per acre |
