Is this an exact measurement?

No, this is a simplified estimation. Actual water requirements depend on many factors, including soil type, humidity, wind, and rainfall. This calculator provides a general baseline to help with irrigation planning.

What is Evapotranspiration (ET)?

ET is the total water lost from the soil surface (evaporation) and from the plant (transpiration). This calculator uses a simplified model based on crop type and temperature to estimate ET.

How should I use this result?
