How to increment a for loop by an arbitrary value?

I am creating a Matlab program that calculates corresponding temperatures for Celsius, Kelvin, Fahrenheit, and Rankine scales. I want to write my code so that it can handle an arbitrary temperature increment (a user-inputted value).
Here is my current code (it currently increments by 1 degree Celsius--I want to change this):
Cstart = -50;
Cend = 100;
for Celsius = Cstart:Cend
Celius = Celsius
Kelvin = Celsius + 273.15
Fahrenheit = 1.8.*Celsius + 32
Rankine = (Celsius+273.15)*1.8
end
plot(Celsius,Kelvin,'r')
hold on
plot(Celsius,Fahrenheit,'b')
hold on
plot(Celsius,Rankine,'g')
legend('Kelvin','Fahrenheit','Rankine','FontSize',20)
xlabel('Temperature in Celsius','FontSize',20)
ylabel('Converted Temperature','FontSize',20)
title('Equivalent Temperatures','FontSize',20)
set(gca,'FontSize',20)
Thank you in advance!

Cstart = -50;
Cend = 100;
step = input('Enter the increment ');
Celsius = Cstart:step:Cend;
%for ii = 1:numel(Celcius)
% Celius = Celsius
Kelvin = Celsius + 273.15
Fahrenheit = 1.8.*Celsius + 32
Rankine = (Celsius+273.15)*1.8
%end
plot(Celsius,Kelvin,'r',Celsius,Fahrenheit,'b',Celsius,Rankine,'g')
% hold on
% plot(Celsius,Fahrenheit,'b')
% hold on
% plot(Celsius,Rankine,'g')
legend('Kelvin','Fahrenheit','Rankine','FontSize',20)
xlabel('Temperature in Celsius','FontSize',20)
ylabel('Converted Temperature','FontSize',20)
title('Equivalent Temperatures','FontSize',20)
set(gca,'FontSize',20)
Moreover, you cannot plot this way. I modified it so that Celcius doesn't stay a scalar. Also, you can skip the looping.

You're welcome. Fontsize 20 is a little bit large for me, but your choice, so I didnot changed that.

I agree, but once I paste it into a document and scale it, usually it needs to be pretty big in order for the labels to not be super tiny.

Also, can you accept the answer when they work for you. You have never accepted a single answer from all the questions you've asked.

How can I get the Celsius value to show up in the Command Window (but not on the graph)?

Type
Celsius
After you have run the code. This will show the Celsius vector on command line.

Okay great! Is there any way to have it show up automatically?

Remove the ';' from Celsius as
Celsius = Cstart:step:Cend
