5 Measuring temperature
Temperature tells us how hot or cold something is. You will see or hear temperatures mentioned in a weather forecast, and will also come across them in healthcare when measuring the temperature of patient.
Temperature is sometimes given in degrees Celsius and sometimes in degrees Fahrenheit.
Hint: You might sometimes see Celsius called ‘centigrade’. Note that Celsius and centigrade are the same thing, referring to the same scale of measurement.
