The Celsius reading equivalent to 70°F is?

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

[ C = \frac{(F - 32) \times 5}{9} ]

In this case, substitute 70°F into the formula:

[ C = \frac{(70 - 32) \times 5}{9} ]

[ C = \frac{(38) \times 5}{9} ]

[ C = \frac{190}{9} ]

[ C \approx 21.11°C ]

Rounding this to a suitable degree gives you approximately 21°C. This matches the answer choice that corresponds to the correct Celsius equivalent for 70°F, confirming that 21°C is the right conversion. Understanding the conversion process is essential for working with temperature in different contexts, especially in fields where precise temperature measurements are critical.
