Meters to the nearest centimeter for people taller than a meter, meters to the 
nearest millimeter for shorter people. Examples:
Enter 185. Display 0.185 and raise a sanity check "Is the baby premature?".
Enter 1.509. Display 1.51 (but store 1.509).
Enter 5.0. Display 5.00 and raise a sanity check "Is this an elephant?".
Enter 5-0. Store 1.524 and display 1.52.
Enter 1-85. Raise an error.

The European standard says to use centimeters and measure the body, not the 
clothing. When making pants, though, I'd use millimeters for all cloth 
dimensions.

I have three Buffs; they came with cardboard heads with the range of head 
circumferences indicated in centimeters.
