WeatherTalk: Celsius temperature scale makes more sense

Each degree in Celsius is a more noticeable difference than each degree Fahrenheit.

If you’ve ever traveled abroad or heard a story about a cold blast or a heat wave hitting another country, you've likely heard the temperature in degrees Celsius. A hot day would be close to 40 degrees Celsius, which is 104 degrees Fahrenheit, while a cold day could get down to -18 degrees Celsius, which would be near zero in Fahrenheit. The discrepancy is due to the difference in the temperature scales.

On the Celsius scale, there are exactly 100 degrees between the freezing point of water and the boiling point of water, while that same difference is 180 degrees on the Fahrenheit scale. The two temperatures are equal at -40 degrees. Forecasts overseas or in Canada may appear much more accurate since a two-degree range in Celsius would give an American forecaster a range of 3.6 degrees Fahrenheit. Interestingly, three degrees Fahrenheit is what meteorologists call an “accurate forecast" when predicting high and low temperatures.
