Convert – 31° Fahrenheit to Celsius.
- 31°F =°C
The Correct Answer and Explanation is :
To convert -31°F to Celsius, you can use the formula:
[
°C = \frac{(°F – 32) \times 5}{9}
]
Substituting -31 for °F:
[
°C = \frac{(-31 – 32) \times 5}{9}
]
[
°C = \frac{(-63) \times 5}{9}
]
[
°C = \frac{-315}{9}
]
[
°C = -35
]
So, -31°F is equal to -35°C.
Explanation
Understanding temperature conversions is crucial in various fields, including science, engineering, and daily life. The Fahrenheit (°F) and Celsius (°C) scales are the most commonly used temperature scales in the world, with Fahrenheit primarily used in the United States and Celsius used in most other countries.
The Fahrenheit scale is based on the freezing point of water being 32°F and the boiling point being 212°F, giving it a 180-degree interval. In contrast, the Celsius scale sets the freezing point of water at 0°C and the boiling point at 100°C, creating a 100-degree interval. This difference in scale definitions necessitates a specific conversion formula.
In the conversion formula provided above, the process begins by subtracting 32 from the Fahrenheit temperature to adjust for the freezing point offset. This result is then multiplied by 5/9 to account for the difference in degree size between the two scales. The multiplication factor reflects that a one-degree change in Celsius is equivalent to a 1.8-degree change in Fahrenheit.
Converting temperatures accurately is essential in various applications, including weather forecasting, scientific research, and cooking. Understanding the relationships between different temperature scales enables clear communication, especially in international contexts where different units are used. Additionally, being proficient in conversions enhances problem-solving skills in science and engineering, where temperature measurements are critical.
