Conversion of Weather Units: 

 1 Dyne is the force which, acting on 1 gram mass for one second, imparts to it a velocity of one centimeter per second.

 1 Millimeter equals .0394 inch.

 1 Micrometer (abbreviated with Greek letter Mu) equals 1 millionth of a meter or .00003937 inch.

 1 Inch equals 2.54 centimeters.

 1Cubic foot equals .028 cubic meters.

 1Gallon equals 3.785 liters.

 1 Pound equals .373 kilograms.

 1 Ton equals 1,000 kilograms.

 1 Inch of rainfall  deposits 225,378 pounds (84,065.994 kilograms) or 112.7 tons (112,700 kilograms) of water on each acre.

 1 Inch of rainfall equals about 6,272,640 cubic inches (522,720 cubic feet, or 14,636.16 cubic meters) of water per acre or 27,154 gallons (102,777.89 liters)of water per acre.

 1 Inch of rain over one square mile equals 17,378,560 gallons of water or 334,540,800 cubic feet.

 1 Knot (nautical mile per hour) equals 6,080 feet, or about 1.15 miles per hour.

 1 Mile per hour equals about .87 Knot.

 1 Kilometer equals .62137 mile.

 1 Meter equals 39.37 inches. 

 Fahrenheit Temperature = (9/5) Celsius + 32.

 Celsius  (formerly Centigrade) Temperature = 5/9 (Fahrenheit  - 32)

 Kelvin Temperature = (Fahrenheit + 459.67) divided by 1.8.

 Fahrenheit Temperature = (Kelvin x 1.8) - 459.67 

 Kelvin Temperature = Celsius + 273.15.

 Celsius Temperature = Kelvin - 273.15.

 200 mb level = about 40,000 feet.

 300 mb level = about 30,000 feet. 

 500 mb (millibar) level = about 18,000 feet.

 700 mb level = about 8,000 feet.

 850 mb level = about 5,000 feet.

 1000 mb level = surface.
