How would weather reporter read 0.103 meter?

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
