The metric system of measurement is logical and an international standard. It is based on units of 10 and makes calculations of distances and other measures very easy. 100 centimeters = 1 meter, 1000 meters = 1 kilometer.
The imperial system of measurement is a total disaster. 12 inches in a foot? Garbage. 6 feet in a fathom? Garbage.
Also, the Fahrenheit system of temperature is foolish. Celsius is easy. Water freezes at 0 celsius. Get it together USA and make this change.
