How to adjust the ratio to compare the data in two variables?

There are two different variables.

A=[107.5383 47.4492 36.4819 26.4964];
B=1.0e+03 * [4.1876 3.5687 3.4444 3.4548];

I want to know the correlation between A and B.

But, it is too large difference between A and B.

in that case, how to adjust?

P.S. I tried to plot those variables

You can transform your data linearly into, for instance, z-scores, to get a "normal" range of values. This does not change the correlation, so the answer by Walter is the one to follow!

A=[107.5383 47.4492 36.4819 26.4964];
B=1.0e+03 * [4.1876 3.5687 3.4444 3.4548];

% z-score transformation
Az = (A - mean(A)) ./ std(A) 
Bz = (B - mean(B)) ./ std(B) 

plot(Az,Bz,'bo')
corr(Az(:),Bz(:))

thank you so much!

>> corr(A(:),B(:))
