Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Water per tree = trunk diameter × entered water factor. Event water multiplies by tree count; seasonal water multiplies by frequency and weeks.

FAQ
Tree Watering Calculator questions
Is one water factor correct for every tree?+
No. Use local horticultural guidance and adjust for species, establishment stage, soil and weather.
Why calculate runtime from emitter flow?+
Runtime converts the target volume into an operating schedule for the installed emitters.
Should rainfall reduce the schedule?+
Usually yes. Effective rainfall and soil moisture should inform irrigation frequency.
