Why do some people use Fahrenheit and others use Celsius?

Answer 1

Most scientific and industrial processes now use Celsius instead of the traditional Fahrenheit scale, and Fahrenheit is only used primarily in three areas :

• Atmospheric temperatures as publicly announced (Celsius equivalents when in written forms)
• Baking and cooking temperatures (to avoid confusion with older publications and users)
• Body temperatures for medical uses (again, to conform to older information sources)

The USA is very resistant to metrication.

The Fahrenheit scale was the primary temperature standard for climatic, industrial and medical purposes in most English-speaking countries until the 1960s. In the late 1960's and 1970's, the Celsius (formerly centigrade) scale was adopted by most of these countries as part of the standardizing process called metrication. Only in the United States and a few other countries does the Fahrenheit system continue to be used, and only for non-scientific use. Most other countries have adopted Celsius as the primary scale in all use, although Fahrenheit continues to be the scale of preference for a minority of people in the UK, particularly when referring to summer temperatures. Most Britons are conversant with both Celsius and Fahrenheit. Resistance to the Celsius system was partly due to the larger size of each degree Celsius, resulting in the need for fractions, where integral Fahrenheit degrees were adequate for much technical work. The lower zero point in the Fahrenheit system reduced the number of negative signs when measurements such as weather data were averaged

Answer 2

For two reasons :

1. To enable their findings to be easily compared with those of other scientists around the world (who use the Celsius or centigrade scale)
2. The change in temperature is connected to other scientific units in the SI or metric system, as part of their defined standard values.
   

Answer 3

Many scientists use the Kelvin scale for temperature measurement because 0K (zero degrees Kelvin) is "Absolute Zero" nothing can be colder, all atomic vibrations cease at 0K.

As the SI system is relatively self contained, the Celsius scale (which has the same difference between one degree and the next as the Kelvin scale) is used so that derived units will be easy to calculate and use in calculations. For example coefficients of thermal expansion and of specific heat are easier to use if they both are based on the same temperature scale.

Answer 4

That is history and politics.

The same belongs to meters, liters, and kilograms.

Answer 5

to measure the temperature. without it we would be lost

Answer 6

The United States uses bothCelsius and Fahrenheit.

Answer 7

Because other parts of the world use Celsius they want to too, so they can compare their results with others without having to covert Fahrenheit to Celsius every time they do a lab.

Answer 8

Fahrenheit is only used in America and a scattering of other countries, notably Jamaica. Fahrenheit is actually the old unit for measuring heat as Celsius is a metric unit.

Answer 9

Because Centigrade or Celsius is in the metric system

Answer 10

Fahrenheit
