You can refer to the following answer: Is it possible to plot the data and show two different scales for the same data using MATLAB 7.9 (R2009b)? and change the code to have another X-axis in the top instead of the Y-axis on the right by using setting XAxisLocation to 'top'and using xlabel for the 2nd axis.
y = 0:0.01:20;
x = 200*exp(-0.05*x).*sin(x);
f = figure;
a1 = axes;
plot(x,y)
xt = get(a1,'XTick');
a2 = copyobj(a1,f);
set(a2,'Color','none')
set(a2,'Ytick',[])
set(a2,'XAxisLocation','top')
converted_values = 2.54*xt;
set(a2,'XTickLabel',converted_values)
xlabel(a1,'X [inches]')
ylabel(a1,'Y [units]')
xlabel(a2,'X [cms]')

How to remove overwritting of one plot over another ??
I have also uploaded the revised ones..
clc
close all
clear
x = 0:0.01:20;
y = 200*exp(-0.05*x).*sin(x);
f = figure;
a1 = axes;
plot(x,y)

Thanks to Srivardhan Gadila ,
I have revised the codes and now things look more better.
%% TOP and bottom x-tick (xlabel) with different scale
%% TOP and bottom x-tick (xlabel)
clc
close all
clear
x = 0:0.01:20;
y = 200*exp(-0.05*x).*sin(5*x);
f = figure;
a1 = axes;
plot(x,y,'LineWidth',2)
grid on
xlabel(a1,'X [inches]')
ylabel(a1,'Y [units]')
xt = get(a1,'XTick');
% a2 = copyobj(a1,f);
% set(a2,'Color','none')
a2 = axes('Position', get(a1, 'Position'),'Color', 'none');
set(a2, 'XAxisLocation', 'top','YAxisLocation','Right');
set(a2,'Ytick',[]) % To hide y-tick
set(a2,'XAxisLocation','top')
converted_values = 3*xt;
%% !!! Do Not use XTickLabel, it results in error, no correct scalling between top and bottom!!
% set(a2,'XTickLabel',converted_values)
set(a2,'XLim',[converted_values(1) converted_values(end)]...
,'XTick',converted_values)
xlabel(a2,'X [cms]')
% Size=[Left Bottom Width Height] % each element ranges from 0 to 1
Size=[0.12 0.12 0.8 0.76];
set(a1,'InnerPosition',Size);
set(a2,'InnerPosition',Size);

Corrections :
  1. Correct scaling between top and bottom xtick (which is a bug while using XTickLabel)
  2. Remove overriding of two plots.
  3. Can see the top-x label
