Shell Ccript Convert Fahrenheit to Celsius Temperature ( Celsius to Fahrenheit Temperature )
Posted in Decision Making » Shell Math
Temperature is a physical property of a system that underlies the common notions of hot and cold; something that is hotter generally has the greater temperature. Temperature is measured with thermometers that may be calibrated to a variety of temperature scales. In most of the world , the degree Celsius scale is used for most temperature measuring purposes. The Celsius scale, is commonly used for scientific work. The Fahrenheit Scale is used in USA and some other countries.
Temperature Conversions
- Fahrenheit to Celsius temperature conversion formula : C = (F - 32) x 5/9
- Celsius to Fahrenheit temperature conversion formula : F = (C x 9/5) + 32
See wikipedia article about temperature conversion formulas.
