Answer :

I'm guessing that you are asking how you read that decimal verbally or in word form.  Here is a trick that I have taught my students to remember how to read the multitude of decimal places that cause them stress.

Starting at the decimal draw a line under the digits to the last number.  Under the decimal write a 1.  For each other digit that remains, place a zero underneath.  You have created a fraction.  Now simply read the number as if it were a fraction.  This would be zero and one hundred three thousandths.

0.103
 1000

Step-by-step explanation:

As we know that decimal is read

0.103 meter as " zero point one zero three meter"

and

if we change into cm , it becomes

0.00103 cm which will be read as " zero point zero zero one zero three cm ".

if we change into mm, it becomes

0.000103 mm which will be read as " zero point zero zero zero one zero three mm".
