are meters an appropriate unit of measurement for your thumb?
why or why not?
They are not because they are too big. Centimeters would be more appropriate.
no. people's thumbs vary in size
No because a meter is like three feet. Your thumb should be measured in centimeters.
Definitely not for MY thumb. A meter is approximately 3.3 feet in length while my thumb is only a few inches. Centimeters would be a more appropriate unit of measurement.
Only if your thumb is a dinosuar
No, as for why, figure it out yourself. Ask helps you with homework, doesn't do it for you.
As a rule of thumb, I use inches.
