I want to show the values with units on the plot
For example, instead of 5.43e-006 sec , I want it to be seen 5.43 μsec.
Or instead of 0.00065 sec, 0.65 msec. Do you have any idea how can I do this?

Why don't you just scale the elements by the appropriate factor?
t = 0:1e-6:0.001;
x = cos(2*pi*1e5*t);
plot(t.*1e6,x)
xlabel('\musec')

% look at this example
close
t0=10^(-8);
t=linspace(t0,t0*10,100)
y=sin(t/t0)
t1=t;tm=max(t1)
unit='s'
if tm<10^(-6)
t1=t*10^6
unit='t(\mus)'
elseif tm>10^(-6) & tm <10^-(3)
t1=t*10^3
unit='t(ms)'
end
plot(t1,y)
set(gca,'xtick',round(linspace(min(t1),max(t1),10)*100)/100)
xlabel(unit)
