What is the temperature conversion for 70 degrees Celsius into Fahrenheit?

To convert Celsius to Fahrenheit, the formula used is:

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

where ( F ) is the temperature in Fahrenheit and ( C ) is the temperature in Celsius.

For 70 degrees Celsius:

1. Multiply 70 by ( \frac{9}{5} ): [ 70 \times \frac{9}{5} = 126 ]

2. Then, add 32 to the result: [ 126 + 32 = 158 ]

Therefore, 70 degrees Celsius converts to 158 degrees Fahrenheit. This confirms that option B is the correct answer.
