Select a city from the weather list. In your scrapbook - record the high temperatures for your city (in celsius). Now - switch your cities temperatures to fahrenheit. Record these temperatures next to the ones above.

There is a formula to explain how to convert from celsius to fahrenheit. Use your data to see if you can work it out. Work with a partner. Hints: > > If you think you've got it, make sure it works with all the data and post your formula below, with your name(s) next to it. > > If you get really stuck - click here to get another hint (but make sure you've tried for a few minutes first)
 * 1) There are 3 different mathematical steps
 * OR: there are 2 steps if you use a fraction
 * 1) In both cases, you must start with a subtraction
 * 2) 0 degrees celsius is 32 degrees fahrenheit.
