The conversion of temperature from Fahrenheit to Celsius is a fundamental concept in physics and chemistry. To convert 68 degrees Fahrenheit to Celsius, we can use the formula: °C = (°F - 32) × 5/9. By plugging in the value of 68 for °F, we get: °C = (68 - 32) × 5/9 = 36 × 5/9 = 20 °C. Therefore, 68 degrees Fahrenheit is equivalent to 20 degrees Celsius.

Temperature Conversion Formula
The formula to convert Fahrenheit to Celsius is a simple yet powerful tool. It allows us to easily switch between the two temperature scales, which is essential in many scientific and practical applications. The formula is: °C = (°F - 32) × 5⁄9. This formula can be applied to any temperature in Fahrenheit to obtain the equivalent temperature in Celsius.
Practical Applications of Temperature Conversion
Temperature conversion is not just a theoretical concept; it has many practical applications in our daily lives. For example, when cooking, it’s essential to know the temperature of the oven or stove in both Fahrenheit and Celsius. This is because different recipes may use different temperature scales, and being able to convert between them is crucial. Additionally, in scientific research, temperature conversions are often necessary to ensure accuracy and consistency in experimental results.
| Temperature Scale | Conversion Formula |
|---|---|
| Fahrenheit to Celsius | °C = (°F - 32) × 5/9 |
| Celsius to Fahrenheit | °F = (°C × 9/5) + 32 |
Common Temperature Conversions
In addition to converting 68 degrees Fahrenheit to Celsius, there are many other common temperature conversions that are useful to know. For example, the freezing point of water is 32 degrees Fahrenheit, which is equivalent to 0 degrees Celsius. The boiling point of water is 212 degrees Fahrenheit, which is equivalent to 100 degrees Celsius. These conversions are essential in many scientific and practical applications, and being able to recall them quickly can be very helpful.
Tips for Memorizing Temperature Conversions
Memorizing temperature conversions can be challenging, but there are several tips that can help. One approach is to practice converting different temperatures back and forth between Fahrenheit and Celsius. This can help you develop a sense of the relationships between the two scales and make it easier to recall specific conversions. Another approach is to use mnemonic devices, such as rhymes or acronyms, to help you remember key conversions.
