## Step-by-Step Solution

### 1. What is the formula to convert Fahrenheit to Celsius?

The formula to convert Fahrenheit to Celsius is: Celsius = (Fahrenheit - 32) × 5/9. This formula allows you to take a temperature in Fahrenheit and convert it to Celsius by subtracting 32 from the Fahrenheit value and then multiplying by 5/9.

### 2. Why do we convert Fahrenheit to Celsius?

Converting Fahrenheit to Celsius is necessary for understanding temperatures in different parts of the world, especially since many countries use Celsius as the standard unit of temperature. It helps in scientific research, weather forecasting, and global communication.

### 3. Is there an easy way to convert Fahrenheit to Celsius in your head?

To quickly estimate Fahrenheit to Celsius in your head, subtract 30 from the Fahrenheit temperature and then divide by 2. This gives a rough estimate but is not as accurate as using the exact formula.

### 4. What is 100°F in Celsius?

100°F is equal to 37.7778°C. You can convert it using the formula: (100 - 32) × 5/9 = 37.7778°C.

### 5. Can Celsius be negative?

Yes, Celsius can be negative. Temperatures below 0°C are considered below freezing and are often observed in winter seasons in many parts of the world.

### 6. What is the freezing point of water in Fahrenheit?

The freezing point of water in Fahrenheit is 32°F. At this temperature, water turns into ice. In Celsius, this is equivalent to 0°C.

### 7. What is the boiling point of water in Celsius?

The boiling point of water in Celsius is 100°C. At this temperature, water turns into steam. In Fahrenheit, this is equivalent to 212°F.

### 8. What is the average human body temperature in Fahrenheit?

The average human body temperature is approximately 98.6°F. This is equivalent to around 37°C in Celsius, although this can vary slightly from person to person.

### 9. How do weather reports use Fahrenheit and Celsius?

Weather reports use Fahrenheit and Celsius to communicate temperatures. In the United States, Fahrenheit is commonly used, while most other countries use Celsius. This allows people to understand the temperature in their preferred units.

### 10. What is absolute zero in Celsius and Fahrenheit?

Absolute zero is the lowest possible temperature where all molecular motion stops. It is -273.15°C in Celsius and -459.67°F in Fahrenheit. This is a theoretical temperature that cannot be physically achieved.

### 11. How do scientists convert Fahrenheit to Celsius?

Scientists convert Fahrenheit to Celsius using the formula: Celsius = (Fahrenheit - 32) × 5/9. This precise formula ensures accurate temperature conversions for scientific research and experiments.

### 12. Can this calculator be used for negative Fahrenheit values?

Yes, this calculator can convert negative Fahrenheit values to Celsius. Simply input the negative Fahrenheit value, and the calculator will provide the corresponding Celsius temperature using the same conversion formula.
