Rainwater Harvesting Calculator
Estimate collected rainwater volume from catchment area, rainfall and supplied efficiency.
Open toolRain Gauge Converter
Find rainfall depth from collected volume and rain-gauge opening area. Provide Collected water volume (mL), Collection opening area (cm²) to compute results directly in your browser. Depth in mm = 10*milliliters/square centimeters. Uniform vertical collection assumed; no evaporation, wind or instrument-calibration correction. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.

Practical Worked Examples for Rain Gauge Converter
These concrete scenarios illustrate how the Rain Gauge Converter processes baseline inputs, comparison checks, and boundary constraints.
Baseline run (Collected water volume (mL) = 100)
Collected water volume (mL) = 100; Collection opening area (cm²) = 100. The displayed output is 10 mm.
Comparison scenario (rain gauge conversion)
Collected water volume (mL) = 75; Collection opening area (cm²) = 150. The displayed output is 5 mm.
Boundary & unit check (Rain Gauge Converter)
When solving for 'rain gauge converter', verify that Collected water volume (mL), Collection opening area (cm²) use consistent units and stay within the documented scope: Depth in mm = 10*milliliters/square centimeters. Uniform vertical collection assumed; no evaporation, wind or instrument-calibration correction. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.
How to Read and Verify the Rain Gauge Converter Output
The output panel reports the exact result derived from Collected water volume (mL), Collection opening area (cm²) alongside any unit or formatting notes.
The result is the rainfall depth in millimeters. Convert a rain-gauge sample volume into equivalent rainfall depth.
The depth follows the opening area; evaporation, wind and instrument calibration are not corrected.
Numerical output shows up to 12 significant digits. Floating-point arithmetic and display rounding can affect the last digits.
- Example input
- Collected water volume (mL) = 100; Collection opening area (cm²) = 100
- Example output
- 10 mm
