Convert 68 °F to °C.
A) 50
B) 15
C) 20
D) 36

Asked by fernando483

Answer (1)

The problem requires converting a temperature from Fahrenheit to Celsius.
The formula for conversion is C = 9 5 ​ ( F − 32 ) .
Substitute F = 68 into the formula: C = 9 5 ​ ( 68 − 32 ) = 9 5 ​ ( 36 ) .
Calculate the Celsius temperature: C = 20 . The final answer is 20 ​ .

Explanation

Problem Analysis We are asked to convert a temperature from Fahrenheit (°F) to Celsius (°C). The given temperature is 68 °F.

Conversion Formula To convert Fahrenheit to Celsius, we use the formula: C = 9 5 ​ ( F − 32 ) where C is the temperature in Celsius and F is the temperature in Fahrenheit.

Calculation Substitute the given Fahrenheit temperature, F = 68 , into the formula: C = 9 5 ​ ( 68 − 32 ) C = 9 5 ​ ( 36 ) C = 9 5 × 36 ​ C = 9 180 ​ C = 20

Final Answer Therefore, 68 °F is equal to 20 °C.


Examples
Temperature conversion is a common task in many real-world scenarios. For example, when traveling to a country that uses Celsius, you may need to convert Fahrenheit temperatures to Celsius to understand the weather forecast. Similarly, in scientific experiments, it may be necessary to convert temperatures between Fahrenheit and Celsius for accurate data analysis. This conversion is also useful in cooking, as some recipes provide temperatures in Fahrenheit while others use Celsius. Knowing how to convert between the two scales allows for easy adaptation of recipes and accurate cooking.
