The conversion of temperature from Fahrenheit to Celsius is a common task in various fields, including science, engineering, and everyday life. To convert 68 degrees Fahrenheit to Celsius, we can use the following formula: °C = (°F - 32) × 5/9. Applying this formula, we get: °C = (68 - 32) × 5/9 = 36 × 5/9 = 20°C. Therefore, 68°F is equal to 20°C.
Understanding the Fahrenheit and Celsius Scales
The Fahrenheit scale is a temperature scale that was widely used in the past, particularly in the United States. It is defined such that the freezing point of water is 32°F and the boiling point is 212°F. On the other hand, the Celsius scale is based on the metric system and is defined such that the freezing point of water is 0°C and the boiling point is 100°C. The Celsius scale is widely used in scientific and technical applications due to its simplicity and ease of use.
Temperature Conversion Formulas
To convert temperature from Fahrenheit to Celsius, we can use the formula: °C = (°F - 32) × 5⁄9. To convert temperature from Celsius to Fahrenheit, we can use the formula: °F = (°C × 9⁄5) + 32. These formulas can be used to convert any temperature value between the two scales.
| Temperature (°F) | Temperature (°C) |
|---|---|
| 32°F | 0°C |
| 212°F | 100°C |
| 68°F | 20°C |
Practical Applications of Temperature Conversion
Temperature conversion is crucial in various fields, including science, engineering, and everyday life. For example, in cooking, it’s essential to know the equivalent temperature in Celsius when following a recipe that uses Fahrenheit. Similarly, in scientific experiments, temperature conversion is necessary to ensure accurate measurements and results.
Real-World Examples of Temperature Conversion
In the medical field, temperature conversion is used to monitor patient temperature, which is critical in diagnosing and treating illnesses. In the food industry, temperature conversion is used to ensure food safety and quality. For instance, the safe minimum internal temperature for cooking poultry is 165°F (74°C), while the safe minimum internal temperature for cooking beef is 145°F (63°C) with a 3-minute rest time.
In conclusion, converting 68°F to Celsius is a straightforward process that involves using the formula: °C = (°F - 32) × 5/9. This conversion is essential in various fields, including science, engineering, and everyday life. By understanding the Fahrenheit and Celsius scales and using the correct conversion formulas, we can ensure accurate measurements and results in our daily lives.
