**Celsius Vs Fahrenheit Scale Overview**

**Celsius Scale Definition**

**Celsius Scale Definition**

The Celsius scale, often referred to as the centigrade scale, represents a temperature scale depending on the freezing and boiling points of water, 0°C and 100°C, respectively.

- In 1742 A.D., the Swedish astronomer Anders Celsius introduced the scale and gave it his name. The sign for this scale is °C.
- The initial design of the Celsius scale placed the melting point of ice at 100°C and the boiling temperature of water at 0°C,but it was eventually reversed to its current configuration.
- The bottom fixed point on this scale is assumed to be 0 degrees Celsius,while the higher fixed point is taken to be 100°C.
- One degree Celsius (1°C) is equivalent to each of the 100 equal parts that make up the area between these two temperatures.
- Water freezes at 0 degrees Celsius but also boils at 100 degrees Celsius,according to the inverted Celsius scale.
- The triple point of Vienna Standard Mean ocean water serves as the foundation of the newer, better Celsius scale, which also incorporates the idea of absolute zero.
- As a result, the triple point of water serves as the foundation for the present understanding of the Celsius scale rather than the freezing point and boiling point of water.
- Absolute zero, or 0K, or -273.15°C, is the lowest temperature that may exist after May 2019. Prior to then, however, 273.16 K, or 0.01 °C, was precisely established as the temperature of water’s triple point.
- On a Celsius scale, the normal body temperature of an adult is 37°C.
- The formula for translating from the Celsius scale to the Fahrenheit scale is °F = (9/5) °C + 32.
- All scientific reasons employ the Celsius scale, which is often used in regions that use the metric system of measurement.

**Fahrenheit Scale Definition**

**Fahrenheit Scale Definition**

A temperature scale called the Fahrenheit scale is based on the fact that water freezes at 32°F and boils at 212°F.

- Daniel Gabriel Fahrenheit, a scientist, invented the scale and gave it his name in 1720. The sign for this scale is °F.
- The temperature of a brine solution with equal parts ice, water, and salt is the lowest defining point on the Fahrenheit scale (ammonium chloride).
- The average body temperature was first calculated at 96°F and then revised to 98.6°F.
- The lower fixed point on this scale is taken to be 32°F, while the higher fixed point is taken to be 212°F.
- Each of the 180 equal portions of the area between these two temperatures represents one degree Fahrenheit (1°F).
- As a result, according to the Fahrenheit scale, water has a freezing point of 32°F and a boiling temperature of 212°F.
- °C = (°F – 32) 5/9 is the formula for converting degrees Fahrenheit to degrees Celsius.
- The Fahrenheit scale’s definition of absolute zero is -459.67° F.
- The earliest universally recognised temperature scale is the Fahrenheit scale. Up to the 1960s, it was common in the majority of English-speaking countries.
- After 1960, this scale was subsequently superseded by the Celsius scale in all save the United States.

Definition |
Celsius scale, or centigrade scale, is a temperature scale that is based on the freezing point of water at 0°C and the boiling point of water at 100°C. | Fahrenheit scale is a temperature scale that is based on the freezing point of water at 32°F and the boiling point of water at 212°F. |

Denoted by |
Celsius scale or simply Celsius is abbreviated as Degree C (°C). | Fahrenheit is abbreviated as Degree F (°F). |

Introduced by or Named after |
It is named after the astronomer ‘Andres Celsius’. | It is named after the physicist ‘Daniel Gabriel Fahrenheit’. |

The freezing point of water |
The freezing point of water or the melting point of ice in the Celsius scale is 0°C. It is the lower fixed point of the scale. | The freezing point of water or the melting point of ice in the Fahrenheit scale is 32°F. It is the lower fixed point of the scale. |

The boiling point of water |
The boiling point of water, as described in the Celsius scale, is 100°C. It is the upper fixed point of the scale. | On the Fahrenheit scale, the boiling point of water is 212°F. It is the upper fixed point of the scale. |

Average human body temperature |
The average human body temperature, as measured in the Celsius scale, is 37°C. | The average human body temperature in the Fahrenheit scale is 98.6°F. |

Absolute zero value |
On the Celsius scale, the absolute zero value is set at -273.15°C. | The absolute zero value in the Fahrenheit scale is -459.67°F. |

Divisions |
The melting and boiling point of water in the Celsius scale is divided into 100 equal divisions, each division representing 1°C. | The melting and boiling point of water in the Fahrenheit scale is divided into 180 equal intervals, each division denoting 1°F. |

Used |
The Celsius scale is widely used in almost every part of the globe. | Fahrenheit scale is mostly used in the United States and some of its territories. |

Conversion |
It can be converted into Fahrenheit by the formula; | Degree Fahrenheit is easily convertible into Celsius by the formula; |

°F = (9/5 × °C) + 32 |
°C = (°F – 32) × 5/9 |
