Americans are already served a great deal of wrong information – as a a content producer, you should be more careful with your articles:

“NOAA charts are in °C, because that’s what climate scientists and all those other nations measure temperatures in – no doubt to make sure that Americans remain uninformed – but you can multiply °C by 1.8 to translate them into our familiar °F temperatures.”

Regarding the statement above, please note that:

“The International System of Units (abbreviated SI from the French Système international d’unités) is the modern form of the metric system and is generally a system of units of measurement devised around seven base units and the convenience of the number ten. It is the world’s most widely used system of measurement, both in everyday commerce and in science.”
