As rainfall and irrigation water use is measured in mm, what is the vol of say 10 mm of rain? - rain irrigation
Moreover, when the supply of irrigation water (internal or commercial), is the amount of water used in mm. None of the "great scientific minds of our time, however, show that the water in terms of volume (gallons or liters). Why is this so?
Farmers can not see the amount of water is 900 mm or 12 inches, but that's what all the programs of literature! And I checked the last time was, no table conversaion mm (length) in liters (volume) to convert, so whay, why insist on misleading information?
Rain Irrigation As Rainfall And Irrigation Water Use Is Measured In Mm, What Is The Vol Of Say 10 Mm Of Rain?

The amount of rainfall can be as mm per hectare of arable or calculated in a customs area or basin.
The equation is:
= Volume of rainfall in the catchment ha x mm of rain
= Volume of rainfall in the catchment area x ha rain
The volume of precipitation in millimeters times the area you are watering. For example, 10 mm (should be 0.01 m) of rain on 1,000 square meters will be 0.01 x 1000 m ^ 2 = 10 m 3 of water = 10,000 liters.
The reason, why should only be thrown rain gauge shows the amount of rain in a given area to calculate the volume would have to know the entire area covered in the rain makes it impossible to get an accurate answer because the rain does not fall systematically entire regions fall. The indicator is a simple way to drop the farmers estimate the amount of rain that their specific fields during the storm. The length of a rain gauge is only one dimension, it is already, if the diameter of round or long, wide and high when it square. Thus it can be calculated.
The volume is the entire area as a result of which is a small box that 1200 inches (100 feet) of 2.400 inches (200 m) and the doctrine there is rained 3 inches (the average) in all fields, then the volume of water is or 1200X2400X3 = 8,640,000 cubic feet, or 5,000 cubic feet.
There are 231 cubic inches per gallon. Since a cubic foot is 12 by 12 by 12 inches, a cubic foot 1728 cubic centimeters. For example, a cubic foot = 1728cubic inches = (1728/231) gallon = 7.48 liters.
Thus, the volume in liters = 37.400 gallons 7.48X5000 fell in this area, especially during the rain event, which has only 3 inches of rain across the country.
