Imperial Measurement System
An ergonomic system of measurement based on everyday life.
Proof:
-
Liquid Volume
-
Pint (idea)
A pint is precisely the maximum amount of liquid which can be ingested in one gulp by an average human being.
-
-
Gallon (idea)
As much liquid as the average human being can drink without throwing up.
-
- Weight (humans don't know about mass)
-
Stone (idea)
Well, clearly the approx. weight of the biggest rock you can clasp in a human hand.
-
- Tonne (idea)
The weight of the biggest rock that humans can move co-operatively.
-
- Length (where the rule is most patent)
-
Foot (idea)
Hmm... The length of a human foot?
-
- Yard (idea)
The length of a human stride.
-
- Mile (idea)
The longest distance that can be considered a short walk by a human from anywhere else.
So it shouldn't come as much of a surprise that people experienced in the use of Imperial measurements have trouble getting to grips with the Metric System, should it?
