Bon jour, Grandpapa.
This is my hundredyearold grandfather centimeter.
I know he looks old but he can measure ten times as fast as I can.
You see, 1 centimeter is the same length as 10 millimeters.
A paper clip thirtytwo milimeters long is a little more than three centimeters long.
I guess it's time for you to meet my godfather  the meter. He's a very important part of the system  the metric system, that is.
I warn you, he measures a thousand times what I do.
I told you he was big.
Oh, dear. I'm just too small to be of any use in talking about the meter.
Excuse me a moment. I need to use a trick taught to me by Alice you know Alice through the Looking Glass, Alice in Wonderland.
There, that's better.
