1 Fahrenheit (°F)

-17.22222 Celsius (°C)

Fahrenheit : Fahrenheit (symbol: °F) is a unit of measurement for temperature. In most countries during the mid to late 20th century, the Fahrenheit scale was replaced by the Celsius scale. However, it remains the official scale of the United States, Cayman Islands and Belize.

Celsius : Celsius, also known as centigrade, is a unit of measurement for temperature. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty. In 1948, the 9th CGPM and the CIPM formally adopted "degree Celsius".

FAQ about Fahrenheit to Celsius Conversion

0 degrees Fahrenheit is equal to -17.77778 degrees Celsius:

0 °F = -17.77778 °C

The temperature T in degrees Celsius (°C) is equal to the temperature T in degrees Fahrenheit (°F) minus 32, times 5/9, that conversion formula:

T(°C) = (T(°F) - 32) / 1.8

50 Fahrenheit is equal to 10 Celsius:

50°F = (50°F - 32) / 1.8 = 10°C

0 Celsius is equal to 32 Fahrenheit:

0°C = 0°C × 9/5 + 32 = 32°F

T(°C) = (86(°F) - 32) / 1.8 = 30°C

What is the significance of 32 in the Celsius to Fahrenheit conversion formula?
Gulshan Sep 26, 2015 at 14:42 pm
Hi Avery, The significance of the number 32 in the Celsius to Fahrenheit conversion formula is that it represents the offset between the two temperature scales. The formula for converting a temperature from Celsius to Fahrenheit is:
F = (9/5 * C) + 32
Where F is the temperature in Fahrenheit and C is the temperature in Celsius.

What is a formula for the conversion of Celsius into Fahrenheit?
Gulshan Jan 16, 2015 at 10:22 am
Hi Parekh, You multiply °C by 1.8 and add 32 = °F.
T(°F) = T(°C) × 9/5 + 32
Ex. (Celsius to Fahrenheit):
100°C *1.8 +32 = 212°F = boiling point of water.

What is the fahrenheit freezing point and boiling point?
Gulshan Jul 20, 2014 at 21:09 pm
0 degrees celsius = 32 degrees fahrenheit, 100 degrees celsius = 212 degrees fahrenheit
Fahrenheit: 32°F freeze point, 212°F boiling point
Celsius: 0°C freezing point, 100°C boiling point
Kelvin: 273.15K freezing point, 373.25K boiling point

How to convert 68 degrees fahrenheit to degrees celsius?
Gulshan Apr 25, 2014 at 18:45 pm
fahrenheit to celsius conversion formula:
T(°C) = (T(°F) - 32) / 1.8
68 Fahrenheit (°F) =T(°F) - 32) / 1.8 = 20 Celsius (°C)

Is -40 degrees Fahrenheit equal to -40 degrees Celsius?
Gulshan Jan 13, 2014 at 22:43 pm
The temperature T in degrees Fahrenheit (°F) is equal to the temperature T in degrees Celsius (°C) times 9/5 plus 32, that conversion formula:
T(°F) = T(°C) × 9/5 + 32
-40°F= T(-40°C) × 9/5 + 32= -72°C + 32 = -40°C
so is yes!!!

How is fahrenheit related to celsius?
Gulshan Jan 13, 2014 at 20:32 pm
Celsius(°C) and Fahrenheit(°F) represent the same temperature. that conversion formula: Temperature(°C) = (Temperature(°F) - 32) / 1.8, so .
