I have been lecturing basic sciences in African universities, in time when the countries of Africa have been changing their fps system to SI system. A very interesting and challenging period! It took some years to accomplish the change fully.
The European parliament on Tuesday 16 Dec 2008 saved the pint and mile from EU extinction, saving British and Irish drinkers from having to order half litres or drive at under 110 kilometres per hour.
Under the measure, agreed without a vote at a second reading in the Strasbourg chamber, traders will also be able to display imperial and metric measurements side by side in shops and elsewhere.
conversion to the metric system happen in your own house
My friend Jeff obstinately uses Celsius units when describing the weather regardless to whom he's talking. Celsius might be one of the most difficult of day-to-day Metric units for an American because most of us have no clue what to wear based solely on a Celsius reading of the temperature. Is 20° C hot or cold? Most of us don't know without performing a conversion to Fahrenheit first. As it turns out, 20° C is a pleasant 68° F.
Jeff's independent change of habit to using metric temperature units inspired me to do the same; I reconfigured the weather widget on my Google homepage to display metric units. Doing so has increased my familiarity with the range of temperatures from 30° C to 45° C this summer but has done little else to spark a greater comfort with the Celsius unit.
Many issues still surround the use of the Metric System in manufacturing today. In the 70's there was an effort to increase the use of the metric system in the United States. Congress passed the Metric Conversion Act of 1975, then the Omnibus Trade and Competitiveness Act in 1988, making the metric system the preferred method. Today the US still does not consider the metric system as its primary or preferred means of measurement.
Looking more specifically at the manufacturing of fasteners, screw, and bolts metric fasteners are in a large part driven by the Automotive Industry. Let's start with design and engineering. In the 70's many companies were still on draft boards, however today we fully utilize CAD systems which not only let us draw parts to size instead of scale, they easily switch between the english and metric systems of measurement. However specifications are still hard to get in metric, Why is there not a IFI standard for metric hex washer head when one is available in inches?
