Almost the entire world uses the metric system as the system of measurement, with units such as meters for distance, kilograms for mass, and newtons for force. People everywhere use these in their everyday lives, whether buying mushrooms in Paris, France, or weighing yourself in spa in Tahiti. The United States, however, is one of THREE stubborn holdouts that does not. Despite this, scientists here, like their colleagues around the globe, do use the metric system in measurements, reports, and calculations. EXCEPT in meteorology, where it is common to use so-called United States customary units for reporting things such as wind speeds (in knots) and surface temperatures (in degrees Fahrenheit). We are clearly out-of-step with the rest of the world, so should we switch to degrees Celsius (and the rest of the metric system)?
