Units & Systems Should Americans bother with metric? POINT Every country in the world, with the exception of the United States, Burma, and Liberia, use the metric system. Leaders in science, politics, and industry have been trying to convince the U.S. government to make laws that require U.S. schools and businesses to adopt the metric system. However, the United States continues to resist. The time has come for change! counterPOINT Why bother learning the metric system? Other than an occasional 2-liter bottle of soda, when do we ever use the metric system? The speed limit for cars driving in your neighborhood is 35 miles per hour. You get a quarter-pounder at McDonalds. The temperature for a hot day in July is 90 degrees Fahrenheit. The current system is easy enough, so why bother learning a new one? See the timeline of important events in the metrication movement. What do you think of the pace of change?

Hurricane Omar October 13 to 18 Dale Destin Antigua and Barbuda
Tropical Cyclone Report (The Antiguan and Barbudan Experience) Hurricane Omar October 13 to 18 Dale Destin Antigua and Barbuda Meteorological Service May 26, 2009 Report in Brief Omar was a historic tropical cyclone. Since record keeping started in 1851, a tropical cyclone has never formed and intensified into a category four (4) hurricane in the Caribbean Sea, east of 70 degrees west and then move northeastly across the Northeast Caribbean. Omar was the fourteenth named storm of the 2008 Atlantic Hurricane Season, the seventh hurricane and the fourth major hurricane. At its closest point (from the northwest coast), Omar was approximately 148 miles northwest of Antigua, and 130 miles northwest of Barbuda with maximum sustained winds of 135 miles per hour (mph). However, by definition, the hurricane did not strike Antigua and Barbuda; notwithstanding, the islands experienced minimal tropical storm conditions. The system caused severe rainfall, which resulted in disastrous flooding. Most of the flooding took place between 0900 and 1600 UTC (5 A.M. and 12 mid day local time) on the morning of October 16, when in excess of five (5) inches of rain fell in most areas. The flooding caused significant damage to agriculture and roads; however there were no loss of lives. Synoptic History Omar formed as a result of the combination of a tropical wave and the Tropical Upper-level Tropospheric Trough (TUTT) on October 13, 0600 UTC at 15.4 north latitude and 69.0 west longitude; this is about 488 miles west-southwest of Antigua. The TUTT that eventually combined with the wave to form Omar was across the Eastern Caribbean from as early as October 4.

Handout – Unit Conversions (Dimensional Analysis)
1 Handout – Unit Conversions (Dimensional Analysis) The Metric System had its beginnings back in 1670 by a mathematician called Gabriel Mouton. The modern version, (since 1960) is correctly called "International System of Units" or "SI" (from the French "Système International"). The metric system has been officially sanctioned for use in the United States since 1866, but it remains the only industrialized country that has not adopted the metric system as its official system of measurement. Many sources also cite Liberia and Burma as the only other countries not to have done so. This section will cover conversions (1) selected units Basic metric units in the metric and American systems, (2) compound or derived measures, and (3) between metric and length meter (m) American systems. Also, (4) applications using conversions will be presented. mass gram (g) The metric system is based on a set of basic units and volume liter (L) prefixes representing powers of 10. time second (s) temperature Celsius (°C) or Kelvin (°K) where C=K-273.15 Prefixes (The units that are in bold are the ones that are most commonly used.) prefix symbol value giga G 1,000,000,000 = 109 ( a billion) mega M 1,000,000 = 106 ( a million) kilo k 1,000 = 103 hecto h 100 = 102 deca da 10 1 1 -1 deci d = 0.1 = 10 10 1 -2 centi c = 0.01 = 10 100 1 -3 milli m = 0.001 = 10 (a thousandth) 1,000 1 -6 micro μ (the Greek letter mu) = 0.000001 = 10 (a millionth) 1,000,000 1 -9 nano n = 0.000000001 = 10 (a billionth) 1,000,000,000 2 To get a sense of the size of the basic units of meter, gram and liter consider the following examples.

It also explains policy towards 20 mph, motorway and rural speed limits and how speed limits are enforced. Finally, it summarises the policies of successive governments towards speed limits. In built up areas the general speed limit is 30mph; on single carriageway roads it is 60 mph and on dual carriageways, 70 mph. However, highway authorities have the power to vary the speed limits on the roads they control – for example in urban areas, particularly around schools, there has been a growing trend for local highway authorities to reduce the limit to 20 mph.
