What is the Fahrenheit equivalent of a temperature reading of "20°C"?

• A. 60°F
• B. 68°F
• C. 72°F
• D. 75°F

Answer: (B)

To convert a temperature from Celsius to Fahrenheit, you can use the formula: \[ F = \frac{9}{5}C + 32 \] For a temperature of 20°C, you would substitute 20 into the formula: 1. Multiply 20 by 9/5: \[ 20 \times \frac{9}{5} = 36 \] 2. Add 32 to the result: \[ 36 + 32 = 68 \] Therefore, the Fahrenheit equivalent of 20°C is 68°F. This calculation aligns perfectly with the standard method of temperature conversion, confirming that the correct answer is indeed 68°F. Understanding this conversion is important for interpreting weather data accurately, as temperature readings can vary between Celsius and Fahrenheit depending on the reporting system used.

To convert a temperature from Celsius to Fahrenheit, you can use the formula:

[ F = \frac{9}{5}C + 32 ]

For a temperature of 20°C, you would substitute 20 into the formula:

1. Multiply 20 by 9/5:

[ 20 \times \frac{9}{5} = 36 ]

2. Add 32 to the result:

[ 36 + 32 = 68 ]

Therefore, the Fahrenheit equivalent of 20°C is 68°F. This calculation aligns perfectly with the standard method of temperature conversion, confirming that the correct answer is indeed 68°F. Understanding this conversion is important for interpreting weather data accurately, as temperature readings can vary between Celsius and Fahrenheit depending on the reporting system used.
