Converting temperature from Fahrenheit to Celsius is a common task, especially when dealing with weather forecasts, cooking recipes, or scientific applications. The conversion process involves a simple formula that can be applied to any temperature reading in Fahrenheit to obtain its equivalent in Celsius. In this guide, we will focus on converting 118 degrees Fahrenheit to Celsius, providing a step-by-step approach and explaining the underlying formula.
Understanding the Fahrenheit and Celsius Scales
The Fahrenheit scale and the Celsius scale are two different temperature scales used to measure temperature. The Fahrenheit scale was introduced by Gabriel Fahrenheit in 1724, while the Celsius scale, formerly known as the centigrade scale, was introduced by Anders Celsius in 1742. The main difference between the two scales is the point at which water freezes and boils. On the Fahrenheit scale, water freezes at 32 degrees and boils at 212 degrees, whereas on the Celsius scale, water freezes at 0 degrees and boils at 100 degrees.
The Conversion Formula
To convert a temperature from Fahrenheit to Celsius, the following formula is used: (C = \frac{5}{9}(F - 32)), where (C) is the temperature in Celsius and (F) is the temperature in Fahrenheit. This formula applies to all temperature conversions between these two scales, providing an accurate and straightforward method for switching between them.
| Temperature Scale | Freezing Point of Water | Boiling Point of Water |
|---|---|---|
| Fahrenheit | 32°F | 212°F |
| Celsius | 0°C | 100°C |
Now, let's apply this formula to convert 118 degrees Fahrenheit to Celsius. Using the formula C = \frac{5}{9}(F - 32), we substitute F with 118.
C = \frac{5}{9}(118 - 32)
C = \frac{5}{9} \times 86
C = \frac{430}{9}
C \approx 47.78
Easy Conversion Tips
Besides using the formula, there are several online tools and conversion charts available that can simplify the process of converting Fahrenheit to Celsius. For quick conversions, especially for common temperatures, memorizing key equivalents can also be helpful. For instance, knowing that 32°F equals 0°C and 212°F equals 100°C can provide a reference point for estimating other temperatures.
Common Temperature Conversions
For everyday applications, knowing the conversions of common temperatures can be useful. For example, room temperature is often considered to be around 72°F, which is approximately 22.22°C. Similarly, the human body temperature is about 98.6°F, equivalent to 37°C.
- 32°F = 0°C (Freezing point of water)
- 212°F = 100°C (Boiling point of water)
- 72°F ≈ 22.22°C (Typical room temperature)
- 98.6°F ≈ 37°C (Average human body temperature)
In conclusion, converting 118°F to Celsius involves applying the formula C = \frac{5}{9}(F - 32), which yields a temperature of approximately 47.78°C. This guide has provided a detailed explanation of the conversion process, along with useful tips and common temperature equivalents to facilitate easy conversions between the Fahrenheit and Celsius scales.
