You have also heard that the outside temperature is very cold tonight or something like that. You also need to know the temperature of our body when we have a fever. How are all these measurements possible?
Obviously we need some device to measure the temperature. This device is known as a thermometer. The simple definition of thermometer: The device which is used to measure the temperature is known as thermometer.
Because both Celsius and Fahrenheit scales are offset— ie neither are defined as starting at zero. On top of that, for every additional unit of heat energy the Celsius and Fahrenheit scales add a different additional value. The only temperature system that works intuitively — where a doubling of value doubles the energy — is Kelvin, where absolute zero is 0, body temperature is The problem with the Kelvin scale is that the zero end of the scale is too far from human experience to be useful — as anyone who set their room temperature to Degrees Centigrade and degrees Celsius are the same thing.
Format Decimal Fractions. Even in countries like the United States however, Celsius is widely used within the scientific community—it just is not widely used in everyday temperature references. The interval between the freezing and boiling point is divided into equal parts. He chose these values to simplify the degree markings he could make on his instruments, since this difference between the temperatures allowed him to mark degree lines by bisecting the interval six times.
Current use: Until the 's the Fahrenheit scale was the primary scale used in English-speaking countries. Today, most countries around the world use the Celsius temperature scale instead, many having made the change during their metrication processes conversion to using the metric system of units.
