What is 71 degree F in C?
The Correct answer and Explanation is:
To convert Fahrenheit (°F) to Celsius (°C), you use the following formula:°C=(°F−32)×59°C = (°F – 32) \times \frac{5}{9}°C=(°F−32)×95
For 71°F:°C=(71−32)×59°C = (71 – 32) \times \frac{5}{9}°C=(71−32)×95 °C=39×59°C = 39 \times \frac{5}{9}°C=39×95 °C≈21.67°C ≈ 21.67°C≈21.67
So, 71°F is approximately 21.67°C.
Detailed Explanation
Temperature conversion between Fahrenheit and Celsius is essential for understanding different temperature scales. Fahrenheit is mainly used in the United States, while Celsius is the standard in most other countries and in scientific settings.
The formula for converting Fahrenheit to Celsius is based on how these two scales are structured. The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in the early 18th century and defines the freezing point of water at 32°F and the boiling point at 212°F. The Celsius scale, invented by Anders Celsius in 1742, is more straightforward, with water freezing at 0°C and boiling at 100°C.
The formula (°F−32)×59(°F – 32) \times \frac{5}{9}(°F−32)×95 works because the difference between the freezing and boiling points of water is 180 degrees on the Fahrenheit scale (212°F – 32°F) and 100 degrees on the Celsius scale (100°C – 0°C). Therefore, 1 degree Celsius is equal to 95\frac{9}{5}59 degrees Fahrenheit, and vice versa, a 1°F change is equal to 59\frac{5}{9}95 of a degree Celsius.
When you subtract 32 from the Fahrenheit value, you’re accounting for the offset in the freezing points (32°F vs. 0°C). Multiplying by 59\frac{5}{9}95 scales the temperature difference to the Celsius system.
Knowing how to convert between these two temperature scales is particularly useful for international travel, cooking, and scientific experiments, where different measurement systems may be in use.
