After Alix and the Chocolate Factory, here's a story afoot.
Well let me tell you, this is not said that you take your own by reading but you learn things in this post!
I work for two weeks as "Carpenter Helper" with a German who has his kit, Vancouver. I am daily confronted with the imperial measurement system (called standard here) and I'm going to be happy to explain aspects plied ...
Every so by a history of foot ... The basic unit of which is basic football, the basic unit very convenient since at the extreme ends of the legs of all individuals. For the sake of harmony, it does not measure by the famous game "cauliflower" by putting one foot before the other but with a ruler calibrated in foot I do know some important person. (The foot has changed in history, up Carolingian king's foot in France and then the English foot, stabilized at 1 ft = 0.3048 m by international treaty in 1959) Note for the little pic that very respectable encyclopedia Wikipedia article begins with this unit: "The foot is a former unit of length ..." no comment!
In the imperial system, the system works in base 12, a foot is therefore equivalent to 12 inches (inch) sadistic Someone decided we could still cut a inch and smaller pieces, So after we inch, half inch, quarter-inch and possibly eighths of inches and sixteenths of an inch.
Let us here in terms of the new unit length as in the construction, use the little yard or miles!
One thing quite amusing here is that Canada is officially passed to the metric system for a long time but nobody uses in the construction ... Or only for the minutes of contest public or lengths are then converted to meters at the last moment, giving quotes to decimals everywhere. Cons by some measure passed in meter course. We talk about the altitude of the mountains in meters (cons is measured by its size in inches!) distances on the road or in town in meters and speed in kilometers per hour. For the small historical note, point out that at the base, the meter is intended as a measure outcome of nature (1m = one ten-millionth part of a quarter of a meridian), since physicists are calibrated over a length wave of radiation after the isotope krypton-86, then the distance traveled by light in vacuum for some time (very short and it is not interesting ;-)
Regarding the practical aspect, from the moment we have in a measurement system, no matter where the goal is to make themselves understood and to have the same reference. I have not had a problem particular to move the foot. I practice every day even my mental arithmetic as it is by no cons so easy to find the middle of a stick of 25'3 / 4''(I'll let you do the exercise in cold! ) but the hardest part for me was to understand the action when I cried from the top of the stairs with his CBC radio one at the bottom ...
Ultimately, the experience is great and more units, I learn the vocabulary gradually especially if the building ... something that I hope will be helpful ...
