# Celsius to Fahrenheit

In this section, we will learn **Celsius to Fahrenheit** or **Â°C to Â°F** conversion with example in detain. Before moving to the conversion, letâ€™s understand the definition of **Celsius** and **Fahrenheit.**

### Celsius

Celsius is the unit to measure the temperature. It is also known as Centigrade. The symbol Â°C (read as **degree Celsius** or **Centigrade**) represents it.

Both Centigrade and Celsius are the naming convention. There is **no difference** between Centigrade and Celsius. The Celsius invented by the **Andes Celsius**. It is also called Centigrade because the scale defined between 0 to 100 degrees. It is used in most countries.

### Fahrenheit

It is also a unit to measure the temperature. It is represented by the symbol Â°F (read as **degree Fahrenheit**). The German physicist **Daniel Gabriel Fahrenheit** suggested the Fahrenheit scale. It is used in the United States.

### Difference between Celsius and Fahrenheit

In the Celsius scale, **0Â°C** represents the **melting point** of the ice, while **100Â°C** represents the **boiling point** of water. The absolute zero in the Celsius scale is **273.15Â°C.**

In the Fahrenheit scale, **32Â°F** represents the **melting point** of the ice, while **212Â°F** represents the **boiling point** of water. The absolute zero in the Fahrenheit scale is **459.67Â°C.**

### Celsius to Fahrenheit Conversion Formula

OR

Where **T** is the temperature that we want to convert.

We can write the above formula as following:

**OR**

Instead of Â°C, put the temperature which you want convert.

Letâ€™s see how to convert Celsius to Fahrenheit using the above formula.

**Example 1: Convert 45Â°C to Fahrenheit.**

**Solution:**

Â°F = 45 * 9/5 + 32 Â°F = 45 * 9/5 + 32 Â°F = 81 + 32 Â°F = 113

**The temperature 45Â°C is equal to 113Â°F.**

The following table describes the typical temperature in Celsius and Fahrenheit.

### Other methods to Convert Â°C to Â°F

We can also use the following methods to convert Â°C to Â°F.

- We use the formula
**Â°F = (Â°C * 1.8) + 32**to convert Celsius to Fahrenheit. To make the formula easier, follow the steps that generate a new formula.- Multiply the temperature (Â°C) by
**2.** - Subtract
**10%**of the above resultant. - At last, add
**32**in the resultant.

Letâ€™s see the above steps in terms of formula.

Â°F = (Â°C * 2) â€“ less 10% + 32 - Multiply the temperature (Â°C) by

#### Note: It works only for Â°C to Â°F conversion.

**Example 2: Convert 34Â°C to Â°F.**

**Solution:**

Â°F = (34 * 2)-10% + 32 Â°F = (68) - 6.8 + 32 Â°F = 61.2+ 32 Â°F = 93.2

**The temperature 34Â°C is equal to 93.2Â°F.**

- In the above table, we have seen that
**-40Â°C equal to -40Â°F**. It means both scales cross each other at 40Â°.**Add 40**to the temperature that we want to convert.**Multiply**the resultant by**9/5.****Subtract 40**from the resultant.

**Example 3: Convert the normal body temperature into Fahrenheit (Â°F).**

**Solution:**

Normal body temperature in Â°C is 37. 37 + 40 = 77 77 * 9 / 5 = 138.6 138.6 - 40 = 98.6

**The normal body temperature in Â°F is 98.6. **

- It is a quick way to convert Â°C to Â°F. It does not give the accurate value. In this method, we just
**double the temperature**that we want to convert and**add 30**to the resultant.

Letâ€™s see some examples.

60Â°C = 60 *2 + 30 = 150Â°F (high by 10Â°)0Â°C = 0 *2 + 30 = 30Â°F (low by 2Â°)-10Â°C = -10 *2 + 30 = 10Â°F (low by 4Â°)10Â°C = 10 *2 + 30 = 50Â°F (accurate)
