Scripts for conversion between Fahrenheit, Celsius, and Kaishi (absolute temperature)

There are different mathematical formulas in the script for converting between Fahrenheit, Celsius, and Kaishi (absolute temperature. The input temperature can be either Fahrenheit, Celsius, or Kaishi (absolute temperature ). Code: 01 #! /Bin/sh0203 # convertatemp. sh -- Temperature Conversion script 04 # allow users to input Fahrenheit... there are different mathematical formulas in the script for converting between Fahrenheit, Celsius, and Kaishi (absolute temperature.

The input is a numeric value with a suffix indicating the unit. In the future, you will see the same single-letter suffix in 66th scripts, which will convert the currency value. Running result: 01. /convertatemp. sh02Usage: convertatemp. sh temperature [F | C | K] 03 where the suffix: 04F indicates input is in Fahrenheit (default) 05C indicates input is in Celsius06K indicates input is in Kelvin07 08. /convertatemp. sh 100c09Fahrenheit = 212.0010 Celsius = 10011 Kelvin = 373.1512 13. /convertatemp. sh 100k14Fahrenheit =-279.6715 Celsius =-173.1516 Kelvin = 100 analysis script: You can also add an option to the script. Then you can run it like this:./converatemp. sh-c 100f to get the temperature at a moderate price of 100 degrees Fahrenheit.
