cell array multiplication with number error

Hello

I have an 22930666x1 cell array and i want to multiplie every element with 1*10^-3 but i keep getting the following error:

Undefined operator '*' for input arguments of type 'cell'.

i also tried it with .*

this is how i do it

CHAamv = readtable('C:\Users\soren\Desktop\Bureaublad\school\MAP\ELFmetingen_5juni2020\ELFmetingen_5juni2020\achtergrondMetingen\picoscoop\achtergrond_320uT_low_10secRecord.csv'); 
CHAamv = table2array(CHAamv); 
CHAamv(:,1)=[];
CHAamv(1,:)=[];


CHAaV = CHAamv *(1*10^-3);

i hope someone can explain what my problem is

thanks in advance

Shot in the dark.

 CHAaV = CHAamv{:,:} * 1e-3;

Thanks for the reply but unfortunately it still doesnt work. I get following error

>> CHAaV = CHAamv{:,:} * 1e-3;

Error using *

Too many input arguments.
