Welcome to the coolest (pun intended) guide on temperature conversion. Just like how your mood swings from being as cool as a cucumber to hot as a jalapeño, temperatures too, swing on a scale! But worry not, we’re here to decipher the Celsius, Fahrenheit, and Kelvin conundrum.

The Conversion Formula
The magic formulas for temperature conversion are as follows:
# Celsius to Fahrenheit
F = C * 9/5 + 32
# Fahrenheit to Celsius
C = (F - 32) * 5/9
# Celsius to Kelvin
K = C + 273.15
# Fahrenheit to Kelvin
K = (F - 32) * 5/9 + 273.15
Categories of Temperature Conversion
| Temperature Scale | Range | Level |
|---|---|---|
| Celsius | -273.15 to Infinity | Used worldwide |
| Fahrenheit | -459.67 to Infinity | Mostly used in the US |
| Kelvin | 0 to Infinity | Used in scientific calculations |
Temperature Conversion Examples
Meet John, who enjoys a cool 20°C (68°F), and Jane, who’s braving -5°C (23°F).
| Individual | Temperature in °C | Temperature in °F | Calculation |
|---|---|---|---|
| John | 20 | 68 | 20 * 9/5 + 32 |
| Jane | -5 | 23 | -5 * 9/5 + 32 |
Temperature Conversion Methods
| Method | Advantages | Disadvantages | Accuracy |
