Answer:
Definition of Celsius
Celsius scale is the part of the metric system and is used to measure the temperature in many countries. Celsius was earlier known as centigrade scale; it is denoted as°C (the Celsius scale). This is the easiest method to understand the temperature reading.
Celsius was introduced in mid-1700 by ‘Andres Celsius‘. Taking water as the base, they have set certain standard values, which is clear to figure out. Like the freezing point of water is 0°C and the boiling point is 100°C. The normal human body temperature is 32°C, and the absolute zero value is set at -273.15°C.
As we said that the values are interconvertible, by applying some easy calculations, so here is the way to change the Celsius to Fahrenheit.
°C to °F: Multiply by 9, then divide by 5 and then add 32.
Formula is written as: (°C × 9/5) + 32 = °F or precisely (°C × 1.8) +32.
Example: How to convert 28°C to Fahrenheit (°F).
First step: 28°C × 9/5 = 252/5 = 50.4.
Second step: 50.4 + 32 = 82°F.
Explanation: From the above example we can it is mandatory to explain that why we have converted the temperature by taking the value as 9/5 and then adding with 32. So if we look at the scale of the Celsius and Fahrenheit, their scale starts at 0°C and 32°C (0 vs 32), respectively, so here we have added 32. Secondly, the scale rises at the rate of 100°C and 180°F (100 vs 180), so again we need to multiply, and 180/100 = 9/5. So this is very easy to calculate.
Definition of Fahrenheit
This is another parameter to measure temperature but nowadays used in United States (US) and few of its territories. It was originated by the physicist ‘Daniel Gabriel Fahrenheit‘ in 1724. The relative’s values like freezing and boiling point of water make the difference. According to this parameter, the boiling point of the water is 212°F and melting point 32°F, and so it makes the difference of the 180 degrees exactly.
The Celsius scale and the Fahrenheit scale coincides at -40°, which is same for both. Even normal human body temperature is 96° on this scale and the absolute zero –459.67°F.
Likewise, the values of Celsius to Fahrenheit is interconvertible, and the same can be done from Fahrenheit to Celsius.
°F to °C: Subtract 32, then multiply by 5, then divide by 9.
Formula is written: (°F – 32) × 5/9 = °C or precisely (F – 32)/1.8.
Example: How to convert 98.6° Fahrenheit into Celsius (°C)
First step: 98.6°F – 32 = 66.6.
Second step: 66.6 × 5/9 = 333/9 = 37°C.
And so from the above example, it is easily understandable to convert the given values in Celsius to Fahrenheit
