1. Multiply the Celsius temperature by 9/5: This step accounts for the different size of the degrees in each scale. A degree Celsius is larger than a degree Fahrenheit, so we need to adjust for this difference.
2. Add 32 to the result: This step accounts for the different zero points of the two scales. The freezing point of water is 0°C and 32°F, so we need to add 32 to shift the scale.

This formula might seem intimidating at first, but with a little practice, it becomes second nature. To illustrate its application, let's consider an example: converting 20°C to Fahrenheit.

Using the formula, we have:

°F = (20 × 9/5) + 32

First, multiply 20 by 9/5:

20 × 9/5 = 36

Then, add 32 to the result:

36 + 32 = 68

Therefore, 20°C is equivalent to 68°F. This example demonstrates how the formula can be easily applied to convert Celsius temperatures to Fahrenheit.

Understanding the logic behind the formula can also help you remember it. The 9/5 factor reflects the ratio of the degree sizes between the two scales, and the +32 accounts for the offset in their zero points. By grasping these underlying principles, you can confidently apply the formula in various scenarios.
