# Celsius Formula

The celsius formula helps in the conversion of temperature across three different scales of temperature, Celcius, Fahrenheit, and Kelvin. The celsius, known as the centigrade originally, was renamed celsius by Swedish astronomer Anders Celsius. A thermometer is a device used to measure the temperature and the display unit of temperature is in Celsius. The celsius formula helps in converting Celcius to Fahrenheit. Lets us learn more about the Celsius formula and solve a few examples to understand the concept better.

## Meaning of Celsius Formula

A Celsius formula helps in converting the temperature in degrees into three units - Celsius, Fahrenheit, and Kelvin. To determine the celsius formula, there are various conversion formulas that help in deriving the exact measurement. Let us learn about the different temperature scales- Celsius, Fahrenheit, and Kelvin.

**Celsius:**The Celsius temperature scale is the most often used scale to measure the temperature. The Celsius scale is used by the international system of units (SI). This scale is divided into 100 equal parts called the degrees Celsius and is marked as °C. The freezing point and the boiling point of water are 0° C and 100° C respectively.**Fahrenheit:**Fahrenheit is the most commonly used scale to measure the temperature in the US. The freezing point and the boiling point of water in the Fahrenheit scale measures are 32°F and 212°F respectively.**Kelvin:**The Kelvin scale is used by SI that is equal to 1/273.16 of the thermodynamic temperature. The freezing point and boiling point of water in the Kelvin scale are 273.15°K and 373.15°K, respectively.

## Celsius Formulas

The celsius formulas involve 3 formulas namely - Conversion of Celsius to Fahrenheit, Conversion of Fahrenheit to Celsius, and Conversion of Celsius to Kelvin. Here is a table showcasing the formulas:

Conversion of | Formulas |
---|---|

Celsius to Fahrenheit | (9/5 × °C) + 32 |

Fahrenheit to Celsius | 5/9(°F - 32) |

Kelvin to Celsius | K - 273 |

Where,

- °C is a measure of temperature in degree Celsius
- °F is a measure of temperature in degree Fahrenheit
- K is a measure of temperature in degree Kelvin

## Examples using Celsius Formula

**Example 1: Convert temperature 400 Kelvin to Celsius? **

**Solution:** Given K = 400, using the celsius formula of conversion i.e.

C = K -273

C = 400 - 273

C = 127°C

**Hence, after the conversion, the temperature is 127°C**

**Example 2: The temperature of a body is 60 degrees Fahrenheit. Using Fahrenheit to Celsius formula, find this temperature on the centigrade scale?**

**Solution:** Given, F = 60

Using the celsius formula of conversion from Fahrenheit to Celsius,

C = 5/9(°F - 32)

C = 5/9 × (60 - 32)

C = 15.56 °C

**Therefore, the temperature in centigrade scale is 15.56 °C**

**Example 3: What is 105°F on the Celsius scale? **

**Solution:** Given, F = 105

Using the celsius formula of conversion from Fahrenheit to Celsius,

C = 5/9(°F - 32)

C = 5/9(105 - 32)

C = 40.56 °C

**Therefore, 105°F on the Celsius scale is 40.56 °C**

## FAQs on Celsius Formula

### What is the Meaning of Celsius Formula?

The Celsius formula is used for the conversion of temperature across 3 different units of temperature - Celsius, Fahrenheit, and Kelvin. For Celcius to Fahrenheit conversion, multiply Celcius with (9/5) and add 32. For Fahrenheit to Celcius conversion, subtract 32 from Fahrenheit and then multiply (5/9). For Celcius to Kelvin conversion just add 273 to Kelvin degrees.

### What are Celsius Formulas?

The various conversion Celcius formulas are:

- Celsius to Fahrenheit : F = (9/5 × °C) + 32
- Fahrenheit to Celsius: C= 5/9(°F - 32)
- Kelvin to Celsius: C= K - 273

### How are the two main Degrees Represented in the Celsius Formulas?

The two main Temperature scales that are commonly used and acknowledged in the world for checking the temperature are Celsius and Fahrenheit. We measure boiling water or body heat with the help of a thermometer. Both the degrees Celcius and Fahrenheit are represented differently in the Celsius formulas. Celsius is written as °C (degree Celsius) and °F (degree Fahrenheit)

### Convert Temperature 45°C to Fahrenheit using the Celsius Formula.

The Celsius formula for converting Celsius to Fahrenheit is:

F = (9/5 × °C) + 32

F = (9/5 × 45) + 32

F = 113°F

Therefore, temperature 45°C = 113°F
