9 FOCUSED TOOLS
Irrigation & applied water calculators
Translate selected depths, measured flow and runtime into water quantities.
Choose the right calculation
A water-budget conversion does not establish the crop’s requirement. Use measured flow and effective rainfall where possible. Distribution losses and runoff can make gross application differ from water retained in the root zone.

Irrigation Volume Calculator
Translate a selected irrigation depth into water volume.
Irrigation Runtime Calculator
Find watering duration from a water-volume target and flow rate.
Sprinkler Precipitation Rate Calculator
Convert sprinkler flow and coverage area into an average application rate.
Drip Irrigation Total Flow Calculator
Estimate total nominal flow of equal drip emitters.
Drip Water Per Plant Calculator
Find water delivered per plant during a drip-irrigation interval.
Irrigation Gross Depth Calculator
Account for an assumed application efficiency in a water-depth budget.
Rainfall Irrigation Offset Calculator
Subtract entered effective rainfall from a chosen irrigation-depth target.
Rain Gauge Catch Depth Calculator
Convert collected water volume and opening area into rainfall depth.
Irrigation Energy Cost Calculator
Estimate electricity spending for an irrigation pump run.
Does one millimetre of rain equal one litre?
It equals one litre over each square metre of collection area. Total volume therefore depends on both depth and area.
