Fahrenheit To Celsius

January 24, 2011 by staff 

Fahrenheit To Celsius, There are many online tools that allows to users for convert the value of C to F or F to C like this you check this site … http://www.wbuf.noaa.gov/tempfc.htm
In the formulas below, / means to divide, * means to multiply, – means subtract, + means to add and = is equal. Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit

To convert a Fahrenheit temperature to Celsius:

Tc = (09/05) * (Tf-32)

For example, to convert a temperature of 98.6 degrees Fahrenheit in degrees Celsius F, first subtract 32 from the Fahrenheit temperature to get 66.6. Then you multiply 66.6 by five ninths to get 37 ° C.

To convert a Celsius temperature in degrees Fahrenheit:

Tf = ((05/09) * Tc) +32

For example, to convert a temperature of 100 degrees Celsius to Fahrenheit, first multiply the Celsius temperature reading by nine-fifths to get 180. Then add 32 to 180 and get 212 ° F.

The Celsius temperature scale is still sometimes called the “centigrade” scale. Centigrade means, “consisting of or divided into 100 degrees.” Swedish Astronomer Andres Celsius (1701-1744) developed the centigrade scales for scientific purposes. It has 100 degrees between the freezing point (0 ° C) and boiling point (100 ° C) of pure water to the air pressure in sea level. An international conference on weights and measures voted to name the centigrade scale after its inventor in 1948.

The Kelvin and Rankine scales

Scientists use the Kelvin scale, which is based on the Celsius scale, but has no negative numbers. Zero on the Kelvin scale is considered the absolute zero is, is when all molecular motion stops.

To convert a temperature reading in degrees Kelvin, simply add 273.16 to the Celsius temperature. This explains why scientists temperatures you’ll see references to temperatures on Earth in the range of 300 degrees.

Absolute zero version of the Fahrenheit scale is the Rankine scale. Add 460 degrees Fahrenheit, the temperature to obtain the Rankine temperature.
