Temperature project

Hi
My name is Daniel and I am a 12 year old boy. At my school, Trinity School, my class have to do a project on temperature. Could you please help me because I do not have a lot of infomation about temperature. All I know is that in temperature there are centigrades and faranheight. And that temperature can be used to describe different things like your body temperature. Please help me nrich or anyone else who can help me out.

Daniel,

Let's start with the centigrade scale. I'll write, for example, 10°C to mean 10 degrees centigrade. The scale is chosen so that water freezes at 0°C and boils at 100°C and goes up in increments in between. To give you an idea of some common temperatures:
A cold day might be around 0°C
Room temperature is usually around 18°C
A hot (British) day might be 25°C
Your body temperature is about 37°C
A hot bath might be around 45°C.

The Fahrenheit scale is similar in that it also increases in equal increments. There is a formula which connects the temperature in centigrade, C, to the temperature in Fahrenheit, F:
F = 1.8 × C + 32.

Can you convert the temperatures I've given above into Fahrenheit? At what temperature would the temperature in centigrade and the temperature in Fahrenheit be the same?

I hope this helps you start.

Richard

Drawing a conversion graph for converting between centigrade and Fahrenheit might be useful. Just convert a couple of those temperatures to Fahrenheit, and that should give you enough information to draw the conversion graph.
