Let us go through the temperature scales, to know them in a better way as below.

**The formula to convert Celsius to Fahrenheit is**

°F = [°C 🇽 (9/5) +32]

= [1.8 °C +32]

**Eg:**

Now, let us convert the boiling point of water from °C to ° F.

As you know, the boiling point of water = 100°C.

°F = [(1.8 🇽 100) +32]

= [180 + 32]

** °F = 212°**

The formula to convert Fahrenheit to Celsius is

°C = [(°F -32) 🇽 5/9]

**Eg:**

Now, let us convert the normal body temperature from °F to ° C.

As you know, the normal body temperature = 98.6°F.

°C = [(98.6 -32) 🇽 5/9]

= [ 66.6 🇽 5/9]

** °C = 37°**

**Let us go through some of the FAQs related to degree Celsius & Fahrenheit.**

**1. How much Fahrenheit is 1°C?**

°F = [(1.8 🇽 °C) +32]

= [(1.8 🇽 1) +32]

= [1.8 +32]

°F = 33.8

**1°C is equal to 33.8°F**

**2. What is the concept behind the conversion formula between degree Celsius & Fahrenheit?**

In the Celsius scale, the temperature of melting ice is considered as 0°C & that of boiling water as 100°C. The difference between the two fixed points is equally divided into 100 parts & each part is taken as 1°C.

In the Fahrenheit scale, the temp. of melting ice is fixed at 32°F & that of boiling water at 212°F. The difference between the two fixed points is equally divided into 180 parts (212 - 32=180) & each division is considered as 1°F.

So, when we draw both scales graphically, their top & bottom point over the axis will be the same.

Let us consider an **a**°C. point over the scale as shown below.

When we measure the distance of **a**°C from the base in Celsius scale

= [L ➗100 х a °C]

The same distance over the Fahrenheit scale

= [L ➗180 х (a °F -32)]

Now,

[(L ➗100) х a °C] = [(L ➗180) х (a °F -32)]

Canceling L on both sides,

[a°C ➗100] = [(a °F -32) ➗180]

(a °F -32) = [(a°C ➗100) х 180]

Canceling '**a' **on both sides,

(°F -32) = (9 °C ➗ 5)

°F = [9/5 х °C +32]

**°F = [1.8 х °C +32]**

**3. What is the difference between degree Celsius & degree Centigrade?**

Celcius & Centigrade were the same temperature scale named at different time periods.

In the earlier days, the word Centigrade was used in which Centi refers to 100 divisions within the scale & grade for the gradients.

In 1948, the temperature scale was standardized with a more precise definition & named after the inventor as Celsius.

Nowadays, we use both words depending on our geographical locations, but the official term is Celsius.

**4. At what temp. point both °Celsius & °Fahrenheit will show the same reading?**

The answer is **- 40°**

**Let us check:**

°F = [(1.8 🇽 °C) +32]

= [(1.8 🇽 -40°) +32]

= [ -72 + 32 ]

°F =** - 40°** ✔

**Thank you for going through these calculation steps❤. Have a good day 😄.**
