Making temperature conversions may seem intimidating at first, especially when the conversion involves different temperature scales, like Fahrenheit and Celsius. But, knowing how to convert 20 degrees Fahrenheit to Celsius can come in handy in many situations.
Temperature scales play a vital role in many areas of life including weather forecasting, medical scenarios, and culinary uses. Generally, two major temperature scales, Fahrenheit and Celsius, are utilized throughout the world. Next, we’ll delve into understanding these scales and how to make temperature conversions.
The Concept of Fahrenheit and Celsius
Fahrenheit and Celsius are two important temperature scales used in modern-day life. Named after the physicist Daniel Gabriel Fahrenheit, the Fahrenheit scale is predominantly used in the United States. The Celsius scale, alternatively known as Centigrade, is widely used globally and was named after the Swedish astronomer Anders Celsius.
Both Fahrenheit and Celsius scales represent the freezing point of water and the boiling point. However, these points vary in value on each scale. For example, in Fahrenheit, water freezes at 32 degrees and boils at 212 degrees. contrastingly, on the Celsius scale, water freezes at 0 degree Celsius and boils at 100 degrees.
Converting Fahrenheit to Celsius: The Conversion Formula
Once you understand the temperature scales, learning how to make Fahrenheit to Celsius conversions becomes easier. Whether you’re converting 20 Fahrenheit or any other value, the conversion formula remains the same.
This formula involves subtracting 32 from the Fahrenheit temperature and then multiplying the result by 5/9. So, to convert 20 degrees Fahrenheit to Celsius, the formula would appear as: (20-32) * 5/9 = -6.67 degrees Celsius. Therefore, 20 degrees Fahrenheit is equal to -6.67 degrees Celsius.
Freezing Point of Water: A Quick Look
The freezing point of water is an essential factor when discussing temperature conversions, as they serve as key reference points on both the Fahrenheit and Celsius heat measuring scales.
On the Fahrenheit scale, the freezing point of water is 32 degrees. In contrast, on the Celsius scale, water freezes at 0 degrees, transforming from a liquid state to a solid one. Knowing these reference points can help you understand and convert temperatures between Fahrenheit and Celsius easily.
Zero Degrees: Understanding the Celsius Scale
The Celsius scale, invented by Anders Celsius, considers the freezing and boiling point of water at standard pressure as the two fixed points. Here, the 0 degrees mark represents the freezing point, while the 100 degrees marks the boiling point of water.
Upon converting these values to the Fahrenheit scale, it becomes apparent that 0 degree Celsius is equal to 32 degrees Fahrenheit.
Key Facts about 6.67 Degrees Celsius and 20 Degrees Celsius
As per the conversion formula, 20 degrees Fahrenheit is equivalent to -6.67 degrees Celsius. This temperature falls below the freezing point of water in the Celsius scale. It signifies a cold temperature, adequate for freezing food or forming ice.
Interestingly, 20 degrees Celsius, in contrast, is a comfortable and mild temperature, often associated with temperate, spring-like weather. This temperature is equivalent to 68 degrees Fahrenheit.
When Water Boils: Exploring the Celsius and Fahrenheit Scales
Just as the freezing point of water is a key point on the temperature scale, the boiling point is essential too. This is the temperature at which water transitions from a liquid to a gaseous state.
In the Celsius scale, the boiling point of water is 100 degrees, while in Fahrenheit it occurs at 212 degrees. These figures serve as another crucial benchmark in making temperature conversions between Fahrenheit and Celsius.
Temperature Conversions: Simplifying Fahrenheit to Celsius
Converting temperatures between Fahrenheit and Celsius need not be complex. Once the conversion formula is grasped and the reference points (boiling and freezing point of water) on both scales are known, temperature conversions become much simpler.
For example, to convert 20 degrees Fahrenheit to Celsius, you apply the formula, resulting in -6.67 degrees Celsius. Conversely, to convert Fahrenheit to Celsius for 68 degrees Fahrenheit, the formula reveals it to be 20 degrees Celsius.
