The Fahrenheit and Celsius scales are two widely used temperature scales. While the Fahrenheit scale is primarily used in the United States, most other countries around the world use the Celsius scale. Understanding the conversion between these two scales is essential for various scientific, engineering, and everyday applications.
To convert a temperature from degrees Fahrenheit (°F) to degrees Celsius (°C), the following formula is used:
°C = (°F - 32) x 5/9
Using the conversion formula, we can convert 29 degrees Fahrenheit to Celsius as follows:
°C = (29°F - 32) x 5/9
°C = (-3) x 5/9
°C = -1.67°C (rounded to two decimal places)
Therefore, 29 degrees Fahrenheit is equal to -1.67 degrees Celsius.
Here are some additional conversions for reference:
°F | °C |
---|---|
32 | 0 |
50 | 10 |
77 | 25 |
104 | 40 |
140 | 60 |
212 | 100 |
The conversion between Fahrenheit and Celsius is crucial in various fields, including:
1. Weather Forecast:
"The temperature today is forecast to be 77°F. What is that in Celsius?"
Answer: 77°F = (77 - 32) x 5/9 = 25°C
2. Science Experiment:
"A chemical reaction requires a temperature of 60°C. What is that in Fahrenheit?"
Answer: 60°C = (60 x 9/5) + 32 = 140°F
3. Cooking Recipe:
"A cake recipe calls for an oven temperature of 350°F. I only have a Celsius oven. What temperature should I set it to?"
Answer: 350°F = (350 - 32) x 5/9 = 177°C

1. The Frozen Blanket Thief
In the depths of winter, a man woke up to find his blanket stolen. He angrily stormed out of his bedroom, only to discover his cat shivering on the cold floor. The cat had hidden the blanket, but in its effort to stay warm, it had accidentally taken it away from its sleeping owner.
Lesson: Even the most selfish actions can have unintended consequences.
2. The Mislabeled Medicine
A woman accidentally took a bottle of cough syrup that had been mislabeled as pain reliever. She quickly realized her mistake and called poison control. Fortunately, she was able to get medical help in time.
Lesson: Always check the labels of medications carefully to avoid dangerous mix-ups.
3. The Unheeded Warning
A group of hikers ignored the warnings of park rangers about approaching storm clouds. They were soon caught in heavy rain and strong winds, and one hiker suffered a serious injury.
Lesson: It is important to heed warnings and take necessary precautions, even when you think you know better.

1. How do I convert Celsius to Fahrenheit?
To convert Celsius to Fahrenheit, use the formula:
°F = (°C x 9/5) + 32
2. What is the difference between Fahrenheit and Celsius?
The difference between Fahrenheit and Celsius is the way they measure temperature. Fahrenheit uses a wider range of degrees, while Celsius is based on the freezing and boiling points of water.
3. What is the normal human body temperature in Celsius?
The normal human body temperature is approximately 37°C or 98.6°F.
4. What is the freezing point of water in Fahrenheit?
The freezing point of water is 32°F or 0°C.
5. What is the boiling point of water in Fahrenheit?
The boiling point of water is 212°F or 100°C.
6. What are some common mistakes people make when converting temperatures?
Some common mistakes people make include:
- Forgetting to subtract 32 when converting °C to °F.
- Forgetting to multiply by 5/9 when converting °F to °C.
- Using the wrong conversion formula.
