TEMPERATURE FAHRENHEIT & CELSIUS

WHAT IS TEMPERATURE? Some people say: it is how hot or cold something is Scientists say: measure of how fast the atoms & molecules that make-up a substance are moving. You would need a microscope to see them. What is a microscope?

HOW IS TEMPERATURE MEASURED? A thermometer measures the temperature of something, it shows how hot or cold. Thermometers measures the temperature of the air, our bodies, food, & many other things. There are TWO types: digital and analog Analog is similar to a scale or dial (think of a clock) Digital: electronic The higher the number the hotter the temperature

TEMPERATURE SCALES There are two systems to measure temperature What else has two systems to measure something? Fahrenheit and Celsius The units are degrees…78 degrees What is the symbol for degrees? We use Fahrenheit and other countries use Celsius Fahrenheit was invented in 1714 by Gabriel Daniel Fahrenheit Celsius was developed by Anders Celsius in 1742

COMMON TEMPERATURES TO KNOW TemperatureFahrenheitCelsius Water Boils212 °F100°C Water Freezes32°F0°C Human Body Temp98.6°F37°C Room Temp68°F20°C Absolute Zero °F °C My Favorite75°F23.88°C

CONVERSION FORMULA Celsius to FahrenheitFahrenheit to Celsius 1.8(Celsius) + 32= Fahrenheit Or Celsius × 2 +32= Fahrenheit (Fahrenheit- 32)/1.8 = Celsius Or Fahrenheit –32 ÷by 2=Celsius
