The cornerstone of converting Celsius to Fahrenheit lies in a specific formula. The formula to convert temperature from Celsius ($^{\circ}C$) to Fahrenheit ($^{\circ}F$) is:

$^{\circ}F = (^{\circ}C \times \frac{9}{5}) + 32$

This formula is derived from the relationship between the two temperature scales, where the freezing point of water is $0^{\circ}C$ and $32^{\circ}F$, and the boiling point is $100^{\circ}C$ and $212^{\circ}F$. The fraction $\frac{9}{5}$ represents the ratio of the size of one degree Fahrenheit to one degree Celsius, and the addition of 32 accounts for the difference in the zero points of the two scales. To effectively use this formula, it’s important to understand the order of operations. First, multiply the Celsius temperature by $\frac{9}{5}$, and then add 32 to the result. This ensures an accurate conversion. The formula is universally applicable and can be used for any temperature in Celsius that needs to be converted to Fahrenheit. Understanding the mathematical basis of this conversion helps in appreciating the relationship between the two scales and allows for more intuitive understanding of temperature measurements. Moreover, familiarity with this formula enables quick and accurate conversions in various practical situations, making it a valuable tool for both scientific and everyday applications. The simplicity of the formula belies its importance in bridging the gap between different temperature measurement systems, fostering clearer communication and understanding in a global context.

Now, let's apply the formula to convert $20^{\circ}C$ to Fahrenheit. We will break down the calculation into simple steps for clarity. First, substitute $20$ for $^{\circ}C$ in the formula:

$^{\circ}F = (20 \times \frac{9}{5}) + 32$

Next, perform the multiplication:

$^{\circ}F = (20 \times 1.8) + 32$

$^{\circ}F = 36 + 32$

Finally, add the two numbers together:

$^{\circ}F = 68$

Therefore, $20^{\circ}C$ is equivalent to $68^{\circ}F$. This step-by-step approach makes the conversion process easy to follow and understand. Each step is crucial to arriving at the correct answer, and understanding the sequence ensures accuracy in future conversions. The multiplication step scales the Celsius temperature to the Fahrenheit scale, accounting for the different degree sizes. The addition of 32 then shifts the scale to match the Fahrenheit zero point. By following this process, one can confidently convert any Celsius temperature to Fahrenheit. This practical application of the formula demonstrates its utility and reinforces the understanding of temperature scale conversions. The result, $68^{\circ}F$, is a common temperature in many everyday contexts, making this conversion particularly relevant for practical applications.

Having calculated that $20^{\circ}C$ is equivalent to $68^{\circ}F$, it's helpful to put this result into context.
