Temperature Scales
The degree Fahrenheit (°F) is a unit of temperature named for the german
physicist Gabriel Fahrenheit (1686 - 1736). In the Fahrenheit scale of
temperature the freezing point of water is 32 degrees and the boiling point is
212 degrees placing the boiling and melting points of water 180 degrees apart.
Zero degrees Fahrenheit indicates the lowest temperature Fahrenheit could obtain
by a mixture of ice and salt.
The degree Celsius (°C) is a unit of temperature named for the Swedish
astronomer Anders Celsius (1701-1744) who first proposed it. The Celsius
temperature scale was designed so that the freezing point of water is 0 degrees
and the boiling point is 100 degrees at standard atmospheric pressure. Since
there are one hundred steps between these two reference points the original term
for this system was Centigrade (100 parts).
Formula Fahrenheit to Celsius Conversion
Fahrenheit to Celsius Conversion
Take temperature in Fahrenheit then
subtract 32 from the number. Then multiply the number by 5 then divide by
9.
Example A) Convert 68 Fahrenheit to Celsius. Take 68 subtract 32.
Then multiply by 5. Then divide by 9. Answer is 20 Celsius.
Example B) Convert 110 Fahrenheit to Celcius. Take 110 subtract 32. Then multiply by 5. Then divide by 9. Answer is 43.3 Celsius.
Formula Celsius to Fahrenheit Conversion
Take temperature in Celsius multiply by 9 then divide by 5 then add 32.
Example A) Convert 20 Celsius to Fahrenheit. Take 20 and multiply by 9 then divide by 5. Then add 32. Answer is 68 Fahrenheit.
Example B) Convert 43.3 Celsius to Fahrenheit. Take 43.3 multiply by 9 then divide by 5. Then add 32. Answer is 109.94 Fahrenheit.
