Celsius to Fahrenheit:

A Fahrenheit to Celsius Converter is an essential tool for converting temperature measurements between the Fahrenheit (°F) scale (used primarily in the United States) and the Celsius (°C) scale (used in most other countries). This conversion is crucial for:

• International travel & weather reports
• Scientific experiments & medical applications
• Cooking & baking recipes

Key Conversion Reference

• Freezing point of water: 32°F = 0°C
• Boiling point of water: 212°F = 100°C
• Absolute zero: -459.67°F = -273.15°C

Conversion Formulas

Fahrenheit to Celsius Formula

$$\mathrm{°}C=\frac{(\mathrm{°}F-32)}{1.8}\text{or}\mathrm{°}C=\frac{5}{9}\times (\mathrm{°}F-32)$$

Celsius to Fahrenheit Formula

$$\mathrm{°}F=(\mathrm{°}C\times 1.8)+32\text{or}\mathrm{°}F=(\mathrm{°}C\times \frac{9}{5})+32$$

How to Use a Fahrenheit to Celsius Converter

1. Enter the temperature in Fahrenheit (°F).

2. Click "Convert" (or press Enter).

3. View the result in Celsius (°C).

4. (Optional) Many converters allow reverse conversion (Celsius to Fahrenheit).

Common Temperature Conversions

Fahrenheit (°F)	Celsius (°C)
-40°F	-40°C	(Same in both scales)
32°F	0°C	(Water freezes)
68°F	20°C	(Room temperature)
98.6°F	37°C	(Human body temperature)
212°F	100°C	(Water boils)

Why Convert Fahrenheit to Celsius?

• Travel & Weather – Many countries use Celsius for weather forecasts.
• Science & Medicine – Most global research uses Celsius or Kelvin.
• Cooking – Recipes from different countries may use different scales.

Manual Calculation Example

Problem: Convert 77°F to Celsius.
Solution:

$$\mathrm{°}C=\frac{(77-32)}{1.8}=\frac{45}{1.8}=25\mathrm{°}C$$

So, 77°F = 25°C (a warm day).

Quick Reference Tips

• For rough estimates: Subtract 30 from °F, then halve it (e.g., 100°F ≈ (100-30)/2 = 35°C).

• Key temperatures to remember:

          a. 0°C = 32°F (freezing)
          b. 20°C = 68°F (room temp)
          c. 37°C = 98.6°F (body temp)
