Celsius to Fahrenheit conversion formula

Celsius- Fahrenheit  °F = ( °C * 9/5 ) + 32

Fahrenheit – Celsius  °C = ( °F – 32 ) * 5/9

Absolute Zero-273.15°C-459.67°F
Parity-40.00°C-40°F
Freezing point0°C32°F
Body Temperature37°C98.6°F
Boiling point100°C212°F

Examples of Celsius to Fahrenheit conversion

  1. Convert 10 °C to °F?

Formula  

°F = ( °C * 9/5 ) + 32 

°F = ( 10 * 9/5 ) + 32 = 50 °F

  1. Convert 60 °C to °F?

°F = ( °C * 9/5 ) + 32 

°F = ( 60 * 9/5 ) + 32 = 140 °F

  1. Convert 100 °C to the Fahrenheit scale.

Step I: Multiply the number of degree by 9.

= 100° × 9

= 900°

Celsius to Fahrenheit

Step II: Divide the product by 5.

= 900° ÷ 5

= 180°

Step III: Add 32 to the result.

= 180 + 32

= 212° F

Therefore, 100° C = 212° F

Celsius origin and current use

 Celsius (symbol: °C) 

Celsius is an international unit for measuring temperature. It is defined based on the other unit of temperature Kelvin. Kelvin and Celsius are similar or when can say related since one-degree change in Kelvin correlated with one-degree change in Celsius.

Originally around 1743 until 1954, the celsius scale was based on the freezing point of water which is 0 °C, and the water boiling point that is 100 °C both at standard atmospheric pressure with the use of mercury as the measuring material.

Celsius to Fahrenheit

Originally, the melting point of snow was defined as 100°C and the boiling point of water as 0°C. 

Until this original definition was inverted, Celsius was not widely used as a unit or a scale.

 By 1954, the unit of temperature, “degree Celsius,” and the Celsius scale were once again redefined based on absolute zero (-273.15 °C) and VSMOW (specially purified water). Until 2019, this definition was in use until the kelvin was redefined according to the definitions of the second, meter, and kilogram.

As of late 20th century, most countries use the Celsius scale instead of the Fahrenheit scale. Except for those countries, such as the United States, that have not adopted the metric system, almost all countries use this scale.

Although Celsius is widely used in the scientific community, it is not commonly used in everyday temperature references even in countries like the United States.

Fahrenheit origin and Current use

The Fahrenheit (symbol: °F) 

Before metrication, Fahrenheit was the most widely used unit of temperature. It consists of two fixed values 

There are two points: the freezing point of water, 32°F, and the boiling point of water, 212°F, both at sea level and at standard atmospheric pressure. The interval between these two points is divided by 180°F.

Daniel Gabriel Fahrenheit, a German physicist, developed the Fahrenheit scale in 1724. The initial scale was based on an equal mixture of ice and salt, with 30°F selected as the freezing point of water and 90°F chosen as the normal body temperature. Later, he adjusted the scale so that body temperature was 96°F and ice melting point was 32°F.

 By choosing these values, he simplified the degree lines he could draw on his instruments since the difference between the temperatures allowed him to bisect the interval six times. 

With the advent of the use of boiling and freezing points of water as fixed reference points, the scale was slightly re-defined so that 180 degrees separated freezing and boiling point, resulting in the normal body temperature of 98°F, rather than Fahrenheit’s 96°F.

Celsius to Fahrenheit

From the 1700s until the 1960s, Fahrenheit was the primary scale in English-speaking countries. Most countries around the world now use the Celsius temperature scale instead of Fahrenheit, many of them have converted to the metric system of units during metrication processes.

There are a number of countries, such as the United States (including its unincorporated territory), the Bahamas, Belize, the Cayman Islands, and a few others, that still use the Fahrenheit scale as the official temperature scale.
