It is very easy to demonstrate to a class of Freshman the stupidity of the Imperial System used in the USA.
1. Teach then about a cigarette – a legal length in Texas 2. Tell them about stones once in class and the use it in the exam 3. Use barley corns 4. A llath is a great UK unit – it is legal in the UK so I tell me students it is acceptable here 5. Do all board work in feet and change to inches in the exam -- Then set a math problem – A building weighs 4000000 stone, what is the ground pressure if the building is 2/3 of a cigarette by 200 llaths in kg/ squared bc. Who said you cannot fix stupid. *John Nichols*
