What is the Celsius equivalent of 68°F?

Explanation:
When converting Fahrenheit to Celsius, use the formula C = (F − 32) × 5/9. For 68°F, subtract 32 to get 36. Then multiply by 5/9: 36 × 5/9 = 180/9 = 20. So the Celsius equivalent is 20°C. The other options don’t fit because they correspond to different Fahrenheit values (for example, 21°C is about 69.8°F, 25°C is 77°F, etc.), while the exact calculation gives 20°C.
