Gauge and water level calculator
Calculates the water level from the zero level and the gauge level. The gauge indicates the water level of rivers and other bodies of water and is often mentioned at high tide. The calculation is very simple, the water level is the sum of the zero level and the gauge. The zero level is determined separately for each measuring point, it is below the lowest water level measured over a long period of time so that the gauge does not have negative values.
Please enter two values, the third value will be calculated.
Example: If the zero level is 180 centimeters and the gauge is 35, then the water level is 215 centimeters.
