5. 2. There is only one temperature at which o C and o F are numerically equivalent. Can you find it? See last slide for answer. 3. To convert from o C to o F: multiply by 9, divide by 5 and add 32. Check it on your graph! What do you do to go from o F to o C? 1. Gabriel Daniel Fahrenheit was a German physicist would lived mainly in England and Holland. He devised the scale of temperature that is now named after him. Did you know?
