Final answer:
To convert Fahrenheit to Celsius use the formula C = 5/9 × (F - 32). Similarly, converting Celsius to Fahrenheit is done with F = (9/5 × C) + 32. To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.
Step-by-step explanation:
The temperature conversion from Fahrenheit to Celsius and vice versa involves a mathematical formula that is based on the linear relationship between the two temperature scales. The general formula for converting Fahrenheit (F) to Celsius (C) is C = 5/9 × (F - 32). The reverse formula to convert Celsius to Fahrenheit is F = (9/5 × C) + 32. These formulas are important as they allow us to understand and compare temperature readings in different units. The relationship indicates that a Celsius degree is larger than a Fahrenheit degree because 100 Celsius degrees cover the same temperature span as 180 Fahrenheit degrees, leading to the fraction 9/5 (or 1.8).
When converting into Kelvin (K), you simply add 273.15 to the Celsius value (T (in ℃) + 273.15 = T (in K)), which is based on the absolute temperature scale where 0 K is absolute zero.
