Question

Write a function in bash that takes an input temperature (Celsius or Fahrenheit) from the user converts that temperature Celsius to Fahrenheit, Fahrenheit to Celsius, Celsius to Kelvin and Fahrenheit to Kelvin

Answer 1

Here is a script that takes Celsius from the user and then converts Celsius to Fahrenheit, Fahrenheit to Celsius, Celsius to Kelvin and Fahrenheit to Kelvin

Formula:

Celsius to Fahrenheit - (0°C × 9/5) + 32 = 32°F

Fahrenheit to Celsius - (32°F − 32) × 5/9 = 0°C

Celsius to Kelvin - 0°C + 273.15 = 273.15K

Fahrenheit to Kelvin - (32°F − 32) × 5/9 + 273.15 = 273.15K

echo

echo command in linux is used to display line of text/string that are passed as an argument

read

read command in Linux system is used to read from a file descriptor

#!/bin/bash
functionn () {
    echo -n "Enter temperature (C) : "
    read tc
    tf=$(echo "scale=2;((9/5) * $tc) + 32" |bc)
    tk=$(echo "scale=2;$tc + 273.15" |bc)
    echo "$tc Celsius = $tf Fahrenheit"
    echo "$tc Celsius = $tk Kelvin"
    tc=$(echo "scale=2;(5/9)*($tf-32)"|bc)
    tkk=$(echo "scale=2;(5/9)*($tf-32) + 273.15"|bc)
    echo "$tf Fahrenheit = $tc Celsius"
    echo "$tf Fahrenheit = $tkk Kelvin"


    

    
}
functionn
