What is 66 °F in °C ?
The Correct Answer and Explanation is :
To convert 66 degrees Fahrenheit (°F) to degrees Celsius (°C), you can use the following formula:
[
°C = \frac{(°F – 32) \times 5}{9}
]
Now, plugging in the value:
[
°C = \frac{(66 – 32) \times 5}{9}
]
First, subtract 32 from 66:
[
66 – 32 = 34
]
Next, multiply 34 by 5:
[
34 \times 5 = 170
]
Finally, divide by 9:
[
°C = \frac{170}{9} \approx 18.89
]
So, 66 °F is approximately 18.89 °C.
Explanation
The conversion from Fahrenheit to Celsius is important in various contexts, especially in science, health, and everyday situations. The Fahrenheit scale, primarily used in the United States, defines the freezing point of water at 32 °F and the boiling point at 212 °F. In contrast, the Celsius scale, which is more widely used around the world, sets the freezing point at 0 °C and the boiling point at 100 °C.
The formula for conversion derives from the linear relationship between the two scales. The subtraction of 32 aligns the starting point of both temperature scales, and the multiplication by (\frac{5}{9}) adjusts the scale’s intervals to correspond with the relative temperature changes.
Understanding these temperature conversions is vital in many fields, including meteorology, cooking, and medicine. For example, when cooking, oven temperatures might be given in Fahrenheit, but many recipes around the world use Celsius. In healthcare, the Celsius scale is often used for measuring body temperature, where normal body temperature is around 37 °C (98.6 °F).
Therefore, knowing how to convert between these two scales enhances comprehension and facilitates effective communication across different regions and professions.
