Systems that Don't make Sense

SYSTEMS THAT DON’T MAKE SENSE
By John Ross Harvey

You deal with various systems daily that really defy logic
But that’s the way it’s always been so you
Take it for granted

Batteries: D, C, AA, and AAA

Would it not be simpler to call them A, B, C, and D?
How did AA and AAA ever come to pass?

School grading: 4,3,2,0

4 is 85%up, 3 70-84%, 2 60-69%, 0 less than 60%
Why is there no 1?
1 could be 50-59%
That isn’t a failure in an election, it’s a win!

Clothing sizes: S, M, L, Xl, XXL, XXXL, and XXXXL

Sometimes numbers are less annoying.
Nobody that wears XXXXL wants to see that
Size 60 is probably less traumatic

Shoe sizes:

Why is size 5 men’s equal to size 7 women’s?
Why do kids sizes have no gender differences?
Why do kid’s sizes go up to 13 before an adult 1?
Why don’t adult sizes start at 14?
Why are European sizes more like 168 than 3?
