%This program is supposed to convert tempratur unite to other unit
c=input('kelvin,celsius,fahrenheit ');
switch c
case 'kelvin'
x=input('enter temprature')
C=x-273.5
disp('C')
R=1.8.*x
disp('R')
case 'celsius'
x=input('enter temprature')
K=x+273.5
disp('K')
F=1.8.*x+32
disp('F')
end

Yes, you can. If you are expecting a string input, try adding 's' as a second input to the input function (the second syntax option). Otherwise, you must enter the text in quotes.
c=input('kelvin,celsius,fahrenheit ','s');
Result using your current code and using quotes
kelvin,celsius,fahrenheit "kelvin"
enter temprature80
x =
80
C =
-193.5000
C
R =
144
R
Result using the 's' option
kelvin,celsius,fahrenheit kelvin
enter temprature80
x =
80
C =
-193.5000
C
R =
144
R
