Fahrenheit, Celsius & Kelvin

Temperature  Is a measure of how hot or cold an object is compared to another object.  Indicates that heat flows from the object with a higher temperature to the object with a lower temperature.  Is measured using a thermometer.

Celsius a unit of temperature in the metric system  Water freezes at 0° C.  Water boils at 100° C.  Normal body temperature is 37° C  Room temperature is 21° C.

Kelvin another unit of temperature in the metric system.  The lowest possible temperature is 0 Kelvin (-273 ° C). This is Absolute Zero.  To convert from Celsius to Kelvin: K = C + 273°

Temperature Scales  Fahrenheit, Celsius, and Kelvin reference points for the boiling and freezing points of water.

37+ degrees Celcius 98+ degrees Fahrenheit Body Temperature

A Comparison of Temperatures

How much can we take? Body temperatures above 40 °C (104 °F) are life-threatening. At 41 °C (106 °F), brain death begins, and at 45 °C (113 °F) death is nearly certain. Internal temperatures above 50 °C (122 °F) will cause rigidity in the muscles and certain, immediate death.
