Fahrenheit to Celsius

Fahrenheit to Celsius: A Guide to Temperature Conversion

Fahrenheit and Celsius are two commonly used temperature scales. While Fahrenheit is the standard temperature scale in the United States, Celsius is the standard metric scale used worldwide. Converting temperatures between Fahrenheit and Celsius can be useful for understanding weather forecasts, cooking recipes, and more.

In this article, we will explore the differences between Fahrenheit and Celsius, the formulas for converting temperatures between the two scales, and some common temperature conversions.

Fahrenheit vs. Celsius: What's the difference?

Fahrenheit and Celsius are both temperature scales that measure the amount of heat in a substance or object. However, they use different units of measurement and have different freezing and boiling points.

The Fahrenheit scale uses degrees Fahrenheit (°F) to measure temperature. The freezing point of water is defined as 32°F, and the boiling point of water is defined as 212°F.

The Celsius scale, also known as the centigrade scale, uses degrees Celsius (°C) to measure temperature. The freezing point of water is defined as 0°C, and the boiling point of water is defined as 100°C.

Formulas for Converting Fahrenheit to Celsius

To convert Fahrenheit to Celsius, you can use the following formula:

°C = (°F - 32) × 5/9

This formula involves subtracting 32 from the Fahrenheit temperature, multiplying the result by 5/9, and then converting the result to Celsius.

For example, to convert 68°F to Celsius, you would use the formula:

°C = (68 - 32) × 5/9
°C = 36 × 5/9
°C = 20

Therefore, 68°F is equal to 20°C.

Formulas for Converting Celsius to Fahrenheit

To convert Celsius to Fahrenheit, you can use the following formula:

°F = (°C × 9/5) + 32

This formula involves multiplying the Celsius temperature by 9/5, adding 32 to the result, and then converting the result to Fahrenheit.

For example, to convert 25°C to Fahrenheit, you would use the formula:

°F = (25 × 9/5) + 32
°F = 45 + 32
°F = 77

Therefore, 25°C is equal to 77°F.

Common Temperature Conversions

Here are some common temperature conversions between Fahrenheit and Celsius:

- 32°F = 0°C (freezing point of water)
- 50°F = 10°C
- 68°F = 20°C
- 77°F = 25°C
- 86°F = 30°C
- 98.6°F = 37°C (normal body temperature)
- 104°F = 40°C (high fever)
- 212°F = 100°C (boiling point of water)

Conclusion

Converting temperatures between Fahrenheit and Celsius is a useful skill for understanding weather forecasts, cooking recipes, and more. The formulas for converting temperatures are simple and involve basic arithmetic. It's important to use the correct formula and to be aware of the freezing and boiling points of water on each scale. By understanding Fahrenheit and Celsius, you can better understand the world around you and make informed decisions based on temperature readings.
