What is 69 °F in °C ?
The Correct Answer and Explanation is :
To convert Fahrenheit (°F) to Celsius (°C), you can use the following formula:
[
°C = \frac{(°F – 32) \times 5}{9}
]
Calculating 69 °F in °C:
- Subtract 32 from the Fahrenheit temperature:
[
69 – 32 = 37
] - Multiply the result by 5:
[
37 \times 5 = 185
] - Divide the result by 9:
[
\frac{185}{9} \approx 20.56
]
So, 69 °F is approximately 20.56 °C.
Explanation of the Conversion Process
The Fahrenheit and Celsius scales are two common temperature scales used around the world. The Fahrenheit scale, developed by Daniel Gabriel Fahrenheit in the early 18th century, is primarily used in the United States and a few other countries. In contrast, the Celsius scale, developed by Anders Celsius, is widely used internationally, especially in scientific contexts.
The conversion formula derives from the linear relationship between the two scales. At 32 °F, water freezes, which corresponds to 0 °C. The boiling point of water is 212 °F, or 100 °C. The difference in increments between the two scales contributes to the conversion factor used in the formula: 1 degree Celsius is equivalent to 1.8 degrees Fahrenheit.
Understanding this conversion is vital, especially in contexts like cooking, meteorology, and international travel, where different regions use different temperature scales. When converting temperatures, it’s essential to ensure accuracy, as temperature affects many physical properties and processes, from weather patterns to chemical reactions. Thus, knowing how to convert between these two scales allows for better comprehension and communication of temperature-related information globally.
