So..since we always measure snow in centimeters...we divide our centimeters by 10 and then multiply by four to get your inches. That might be slightly quicker when dealing with odd numbers.

Get yurself a yardstick. We (Americans) don't care about Ms MMs or CMs.

We'll convert when pizzas get measured in centimeters, not before.
