4. Did you know?
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.
2. There is only one temperature at which oC and oF are numerically equivalent. Can you find it? See last slide for answer.
3. To convert from oC to oF: multiply by 9, divide by 5 and add 32. Check it on your graph!
What do you do to go from oF to oC?
