Converting 97.8 Fahrenheit to Celsius using a formula

In the previous article, we learned how to convert Celsius to Fahrenheit. Now, we will learn how to convert Fahrenheit to Celsius. Converting temperatures between Fahrenheit and Celsius is a common activity in daily life and is essential for understanding weather patterns. In this article, we will explain how to use a formula to convert Fahrenheit to Celsius.

Fahrenheit to Celsius conversion formula

The formula to convert Fahrenheit to Celsius is as follows:

C = (F – 32) × 5/9

Where C represents the temperature in degrees Celsius (°C), F represents the temperature in degrees Fahrenheit (°F).

Analysis of the formula

Let's analyze the formula:

• F is the temperature in degrees Fahrenheit.
• 32 is the freezing point of water in degrees Celsius.
• 5/9 is a constant that converts between the Fahrenheit and Celsius temperature scales.

When we convert Fahrenheit to Celsius using this formula, we first subtract 32 from the given temperature in degrees Fahrenheit (F). This gives us the temperature in degrees Celsius (°C). The result is then multiplied by 5/9, which converts the result back to degrees Celsius (°C).

Example of converting Fahrenheit to Celsius

Let's practice converting a specific temperature from Fahrenheit to Celsius.

Input: Fahrenheit (°F)

70°F

Output: Celsius (°C)

Step 1: Subtract 32 from the temperature in F.

70°F – 32 = 38°F

Step 2: Multiply the result by 5/9.

(38°F) × (5/9) = 21.111°C

Therefore, 70°F is equivalent to approximately 21.11°C.

Practice conversion

Now that we understand the formula, let's practice converting a few temperatures from Fahrenheit to Celsius. We will use Python to perform the conversions.

fahrenheit_to_celsius.py

Fahrenheit (°F): 21.9

Celsius (°C):

# Convert Fahrenheit to Celsius

celsius = (fahrenheit - 32) * (5 / 9)

print("The temperature in Celsius is:", celsius)

Output:

The temperature in Celsius is: 16.111111111111112

Practice conversion (続)

fahrenheit_to_celsius.py

Fahrenheit (°F): 68

Celsius (°C):

# Convert Fahrenheit to Celsius

celsius = (fahrenheit - 32) * (5 / 9)

print("The temperature in Celsius is:", celsius)

Output:

The temperature in Celsius is: 34

Conclusion

In this article, we learned how to use a formula to convert Fahrenheit to Celsius. By subtracting 32 from the given temperature in degrees Fahrenheit and multiplying by 5/9, we can convert the temperature to degrees Celsius. We also practiced this conversion with several examples. This skill is useful for understanding weather patterns and performing mathematical calculations.
