Since the relationship between the Celsius and the Fahrenheit is completely proportional, an increase in temperature on the Celsius scale will also result in an increase in temperature on the Fahrenheit scale. The two most significant measuring scales, Celsius and Fahrenheit, have different values. Different temperature units address different ideas related to the relationship between the two.

Relationship between Celsius and Fahrenheit
Since both Celsius and Fahrenheit scales are frequently employed to measure the temperature of liquids, bodies, and other materials, there is a significant connection between them. The proportionate relationship between these two scales illustrates a crucial point. It has been discovered that when the temperature increases by one degree on one scale, the other scale will also experience an increase in temperature (Huda, 2021). If something’s temperature is determined to drop on the Fahrenheit scale, this causes the temperature on the Celsius scale to drop as well.
| Name of the scale | Freezing point | Boiling point |
| Celsius | 0°C | 100°C |
| Fahrenheit | 32°F | 212°F |

Conversion of Celsius to Fahrenheit
It is possible to provide a useful formula that aids in the conversion of temperature values from Celsius to Fahrenheit. The formula for this conversion process is ”F = (9/5*C) + 32”. This formula uses F as the temperature in degrees Fahrenheit and C as a substitute for the given temperature in degrees Celsius that needs to be converted to degrees Fahrenheit (Yaffe, 2022). For instance, the following formula can be applied to obtain the Fahrenheit value of 51°C.
Value of C= 51°C
F = (9/5*51) + 32
F = 123.8°F
If the temperature on the Fahrenheit scale rises, so does the temperature on the Celsius scale. For instance, when the temperature rises from 0°C to 10°C, the corresponding change in Fahrenheit temperature is 32°F to 50°F (Hall, 2020). Instead, raising the temperature by 30°C to 40°C causes the temperature to rise from 86°F to 104°F.
Conversion of Fahrenheit to Celsius
The conversion formula from Fahrenheit to Celsius is ‘C= 5/9 (F-32)’. Additionally, in this calculation, F stands for Fahrenheit temperature and C for Celsius temperature (Sjöberg et al. 2018). For instance, 45°F can be translated to Fahrenheit.
Value of the temperature in Fahrenheit scale: 45°F
C= 5/9 (F-32)
C= 7.22
What is Fahrenheit?
Daniel Gabriel Fahrenheit is recognised for creating this temperature scale. The Fahrenheit scale has the sign ℉. Water has a freezing point of 32°F and a boiling point of 212°F. It is a non-SI unit that is mostly utilised in the Bahamas, Palau, the United States, and several Caribbean nations.

What is Celsius?
The centigrade scale was its original name. Provided by the °C sign. Water has a boiling temperature of 100°C and a freezing value of 0°C.It is the most widely used and preferred temperature scale globally. Based on the Celsius scale, the Kelvin scale is used in scientific research.
Things to Remember
- Degrees Celsius are the unit of measurement for temperature on the centigrade scale.
- Fahrenheit degrees must be used to express the temperature on the Fahrenheit scale.
- On a Celsius scale, the freezing point of water is 0 °C, while on a Fahrenheit scale, it is 32 °F.
- On a Celsius scale, the boiling point of water is 100 °C, while on a Fahrenheit scale, the freezing point is 212 °F.
- There is a 100 degree interval on the Celsius scale and a 180 degree interval on the Fahrenheit scale.
- F = (9 / 5 × C) + 32 is the formula to convert Celsius to Fahrenheit.
- C = 5 / 9 (F − 32) is the formula to convert Fahrenheit to Celsius
Sample Questions
- Convert 30°C to the Fahrenheit scale.
Solution,
The conversion formula for °C to °F is
TF = 9/5(TC) + 32
= 30° × 9
= 270°
= 270° ÷ 5
= 54°
= 54 + 32
= 86° F
Therefore, 30° C = 86° F
- Convert 75°C to the Fahrenheit scale.
Solution,
The conversion formula for °C to °F is
TF = 9/5(TC) + 32
= 75° × 9
= 675°
= 675° ÷ 5
= 135°
= 135 + 32
= 167° F
Therefore, 75° C = 167° F
- Convert 20°C to the Fahrenheit scale.
Solution,
The conversion formula for °C to °F is
TF = 9/5(TC) + 32
= 20° × 9
= 180°
= 180° ÷ 5
= 36°
= 36 + 32
= 68° F
Therefore, 20° C = 68° F
