What is Celsius in 230 degrees Fahrenheit?
A. 120
B. 110
C. 130
D. 200
The correct answer and explanation is:
Correct Answer: A. 110
To convert Fahrenheit to Celsius, we use the following formula: C=59(F−32)C = \frac{5}{9}(F – 32)
Given: F=230∘FF = 230^\circ \text{F}
Apply the formula: C=59(230−32)=59(198)C = \frac{5}{9}(230 – 32) = \frac{5}{9}(198) C=9909=110∘CC = \frac{990}{9} = 110^\circ \text{C}
Detailed Explanation (300 words)
Temperature scales such as Fahrenheit and Celsius are commonly used in different parts of the world to measure temperature. The Fahrenheit scale is primarily used in the United States, while most other countries use the Celsius scale.
The Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F under standard atmospheric pressure. In contrast, the Celsius scale sets the freezing point of water at 0°C and the boiling point at 100°C. Because these two systems use different zero points and scale intervals, conversion between them requires a specific formula.
The formula to convert Fahrenheit (°F) to Celsius (°C) is: C=59(F−32)C = \frac{5}{9}(F – 32)
This formula first removes the Fahrenheit offset of 32 (since 0°C = 32°F), and then scales the result down by a factor of 9/5 to adjust for the difference in the size of each degree unit (since each degree Celsius is larger than a degree Fahrenheit).
For the given value of 230°F:
- Subtract 32 → 230 – 32 = 198
- Multiply by 5/9 → (5 × 198)/9 = 990/9 = 110°C
Thus, 230°F is exactly 110°C.
Understanding how to convert between temperature units is important in science, engineering, medicine, and daily life—especially when cooking, traveling internationally, or using equipment calibrated in a different unit.
