It might be useful for you to know the conversion of units commonly used in meteorology for use in the classroom.
Fahrenheit to Celsius
To convert a Fahrenheit temperature reading to Celsius: first deduct 32 and then multiply the value you get by 5/9.
e.g. 59°F = (59-32)x(5/9) = 27x5/9 = 15°C.
Celsius temperature reading to Fahrenheit
To convert a Celsius temperature reading to Fahrenheit: first multiply by 9/5 and then add 32.
e.g. 20°C = (20x9/5)+32 = 36+32 = 68°F.
To convert inches to millimetres
1 inch = 25.4 mm
To convert millimetres to inches
1 mm = 0.03937 inch
To convert wind-speed units:
[kt = knot; m/s = metres per second; kph =
kilometres per hour; mph = miles per hour]
