Converting temperature from Fahrenheit to Celsius is a common task in various fields, including science, engineering, and everyday applications. The formula to convert Fahrenheit to Celsius is straightforward: °C = (°F - 32) × 5/9. Let's apply this formula to convert 118 Fahrenheit to Celsius.
Understanding the Conversion Process
The conversion process involves subtracting 32 from the Fahrenheit temperature and then multiplying the result by 5⁄9. This formula is derived from the fact that the freezing point of water is 32°F and 0°C, and the boiling point of water is 212°F and 100°C. By using this formula, we can accurately convert any Fahrenheit temperature to Celsius.
Applying the Conversion Formula
To convert 118 Fahrenheit to Celsius, we plug the value into the formula: °C = (118 - 32) × 5⁄9. First, subtract 32 from 118, which gives us 86. Then, multiply 86 by 5⁄9. This calculation yields 47.78°C. Therefore, 118 Fahrenheit is equivalent to approximately 47.78 Celsius.
| Temperature Scale | Temperature Value |
|---|---|
| Fahrenheit | 118°F |
| Celsius | 47.78°C |
Key Points
- The formula to convert Fahrenheit to Celsius is °C = (°F - 32) × 5/9.
- Applying this formula to 118°F yields a temperature of approximately 47.78°C.
- Precise temperature conversions are essential in scientific and engineering applications.
- In everyday contexts, temperatures may be rounded for simplicity, but accuracy is crucial in technical fields.

Practical Applications of Temperature Conversion
Temperature conversion is vital in numerous fields, including cooking, where recipes often list ingredients and cooking temperatures in either Fahrenheit or Celsius. In scientific research, accurate temperature control and measurement are critical for the validity of experiments. Engineers also rely on precise temperature conversions when designing systems that involve heat transfer or temperature-sensitive materials.
Historical Context of Temperature Scales
The development of temperature scales dates back to the early 18th century, with Gabriel Fahrenheit introducing the Fahrenheit scale in 1724. Later, in 1742, Anders Celsius proposed the Celsius scale, which would eventually become the standard for scientific and international use. The ability to convert between these two scales has become increasingly important as global communication and collaboration in science and technology have grown.
Given the widespread use of both Fahrenheit and Celsius scales, being able to convert between them is a valuable skill. Whether for scientific research, engineering applications, or everyday use, understanding how to convert temperatures accurately enhances one's ability to communicate and work effectively across different contexts and countries.
