Current use: The Celsius scale replaced the Fahrenheit scale in most countries in the mid to late 20 th century. Almost all countries around the world use this scale, except for those in which the metric system has not been adopted, such as the United States.
What is the normal temperature of a human body?
Later, when using the freezing and boiling points of water as fixed reference points for thermometers became popular, the scale was slightly re-defined such that there would be 180 degrees separating freezing and boiling point, resulting in normal human body temperature being approximately 98°F, rather than Fahrenheit's 96°F.

What is zero degrees?
On the scale of Fahrenheit's scale, zero degrees was determined as the temperature of a temperature-stable brine solution of ice and water and ammonium chloride as well. He based the scale on the temperature which was average of the human body that is which he originally calculated at 100 degrees.
What is the normal temperature of a person?
The average which is of the normal body temperature is generally said to be accepted as 98.6°F that is 37°C. Some studies have shown that the "normal" body temperature can have a wide range which is from 97°F that is 36.1°C to 99°F that is 37.2°C. A temperature that is said to be over 100.4°F that is 38°C most often means you have a fever caused by an infection or we can say illness.

What is the unit of temperature?
The Kelvin Temperature Unit. You may have heard of temperature being measured according to kelvin. Indeed, if you're involved in the sciences, you probably use kelvin. Kelvin is a bit different than Fahrenheit and Celsius. Celsius and Fahrenheit are both temperature scales, measuring temperatures in degrees.
How many kelvins is 10 degrees Celsius?
If the outside temperature is 10 degrees Celsius, then it is 283.15 kelvin. That's easy enough. Fahrenheit is a bit trickier. Take your degrees Fahrenheit, subtract 32, divide by 1.8, and finally add 273.15. Here's a quick example: Say it is 100 degrees Fahrenheit outside. Subtract 32 from 100 to get 68.
