The standard area is 1 m^2 and rainfall in mm refers to a prism
having a base of 1 m^2 and high the mm of rainfall
So the mm of rainfall are equvalent to liters/m^2

The rain gauge is the standard method of collection. This has to be sited in a location, which is representative of the rainfall area to be measured. Often a network of sites will be integrated to cover average rainfall over a large area. Rainfall at any one place against time is expressed in terms of the depth to which it would cover the surface locally, assuming there was no loss by evaporation or run-off. The rain gauge is often used in conjunction with other instruments for a full picture of local climatic conditions.
Munro offer a range of precision rain gauges to meet all applications, all manufactured to a British Meteorological Office specification, ensuring accurate rainfall collection and measurement.
Rainfall is defined as the depth of water that crosses a horizontal period over a given length of time and is an integral part of the hydrologic cycle. Students can determine the rainfall of a given area through the use of a rain gauge.
