How to convert from Celsius to Fahrenheit
It is ease to convert a temperature value from Celsius to Fahrenheit by using the formula below:
|[°F] = [°C] × 9⁄5 + 32|
|Value in Fahrenheit = Value in Celsius × 9⁄5 + 32|
To change 39.9° Celsius to Fahrenheit, just need to replace the value [°C] in the formula below and then do the math.
- Write down the formula: [°F] = [°C] × 9⁄5 + 32
- Plug the value in the formula: 39.9 × 9⁄5 + 32
- Multiply by 9: 359.1⁄5 + 32
- Divide by 5: 71.82 + 32
- Add 32: 103.82° = Value in Fahrenheit (answer)
Using this converter you can get answers to questions like:
- How many degrees Fahrenheit are in 39.9 Celsius?
- 39.9 Celsius is equal to how many Fahrenheit?
- How to convert Celsius to Fahrenheit?
- What is the formula to convert from °C to °F? among others.
Definition of Celsius
The Celsius scale was invented in 1742 by the Swedish astronomer Anders Celsius. It was initially defined by the freezing point of water and later changed its definition as being the melting point of ice. 100° C was defined as the boiling point of water. The Celsius scale is a derived scale once its defined in relation to the Kelvin temperature scale. 0 (zero) °C is exactly equivalent to 273.15 K, with a temperature difference of 1 °C equivalent to a difference of 1 K, meaning the unit size in each scale is the same.
The Celsius temperature scale is sometimes referred to as the 'Centigrade' scale. Centigrade means divided into 100 degrees. The following formulas can be used to convert a temperature from Celsius (°C) value to other temperature scales:
|Celsius to Delisle||[°De] = (100 − [°C]) × 3⁄2|
|Celsius to Fahrenheit||[°F] = [°C] × 9⁄5 + 32|
|Celsius to Kelvin||[K] = [°C] + 273.15|
|Celsius to Newton||[°N] = [°C] × 33⁄100|
|Celsius to Rankine||[°R] = ([°C] + 273.15) × 9⁄5|
|Celsius to Reaumur||[°Ré] = [°C] × 4⁄5|
|Celsius to Romer||[°Ro] = [°C] × 21⁄40 + 7.5|
Definition of Fahrenheit
The F scale was invented by Fahrenheit, a German engineer, physicist and glass blower who also invented the mercury thermometer.
Fahrenheit is a temperature scale where the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling point 212°F (at standard atmospheric pressure). This puts the boiling and freezing points of water exactly 180 degrees apart. The following formulas can be used to convert a temperature from Fahrenheit (°F) value to other temperature scales:
|Fahrenheit to Celsius||[°C] = ([°F] − 32) × 5⁄9|
|Fahrenheit to Delisle||[°De] = (212 − [°F]) × 5⁄6|
|Fahrenheit to Kelvin||[K] = ([°F] + 459.67) × 5⁄9|
|Fahrenheit to Newton||[°N] = ([°F] − 32) × 11⁄60|
|Fahrenheit to Rankine||[°R] = [°F] + 459.67|
|Fahrenheit to Reaumur||[°Ré] = ([°F] − 32) × 4⁄9|
|Fahrenheit to Romer||[°Ro] = ([°F] − 32) × 7⁄24 + 7.5|
