All people should
know that things are measured differently. In the U.S., things are measured in
inches, pounds, quarts, Fahrenheit, etc. That is the American system. Other
countries use the Metric system, in which things are measured by centimeters,
kilograms, liters, and Celsius. Meteorologists and others who study the weather
need to be able to convert from the American system to the Metric system. For
example, one inch of rain is the same as 2.54 centimeters of rain. Forty-three degrees
Fahrenheit is the same as six degrees Celsius.
