What is 66 °F in °C?

Temperature conversion between Fahrenheit (°F) and Celsius (°C) is a common requirement in various fields, including science, engineering, and everyday life. The Fahrenheit and Celsius scales are used to measure temperature, but they have different starting points and increments. The Fahrenheit scale is primarily used in the United States, while the Celsius scale is used in most other countries.

Explanation:

To convert a temperature from Fahrenheit (°F) to Celsius (°C), you can use the following formula:

$$°C = \frac{5}{9} \times (°F - 32)$$

Where:

• °F is the temperature in Fahrenheit

• °C is the temperature in Celsius

Answer:

For 66 °F, the conversion to Celsius is calculated as follows:

$$°C = \frac{5}{9} \times (66 - 32)$$ $$°C = \frac{5}{9} \times 34$$ $$°C ≈ 18.89$$

So, 66 °F is approximately 18.89 °C.
