Convert -3 Fahrenheit to Celsius
The Correct Answer and Explanation is:
To convert -3°F to Celsius, we use the formula:
[
C = \frac{5}{9} \times (F – 32)
]
Where:
- (C) is the temperature in Celsius
- (F) is the temperature in Fahrenheit
Now, let’s substitute -3°F into the formula:
[
C = \frac{5}{9} \times (-3 – 32)
]
[
C = \frac{5}{9} \times (-35)
]
[
C = \frac{-175}{9}
]
[
C \approx -19.44^\circ C
]
So, -3°F is approximately -19.44°C.
Explanation:
The Fahrenheit and Celsius scales are two temperature systems used worldwide. The Fahrenheit scale is primarily used in the United States, while Celsius is used in most other parts of the world. The two scales have different starting points and increments.
The formula for converting Fahrenheit to Celsius, (\frac{5}{9} \times (F – 32)), works by first adjusting the Fahrenheit value down to account for the difference in zero points between the two scales. In the Fahrenheit scale, 32°F represents the freezing point of water, whereas in the Celsius scale, 0°C represents the freezing point.
Once we subtract 32 from the Fahrenheit temperature, we adjust the result by multiplying by (\frac{5}{9}), which is the ratio of the size of the Fahrenheit degree to the Celsius degree. Since each Celsius degree is larger than a Fahrenheit degree, this step ensures the correct scaling between the two units.
For example, -3°F is much colder than 0°F, and when converted to Celsius, it results in a negative value of approximately -19.44°C. This indicates a very cold temperature, below freezing in both scales. This conversion process allows for a better understanding of temperature across different regions that use different measurement systems.
