Converting temperature from Fahrenheit to Celsius is a common task, especially in scientific and culinary applications. The Fahrenheit scale and the Celsius scale are two different temperature scales that have different zero points and intervals between units. To convert 47 degrees Fahrenheit to Celsius, we use the formula: °C = (°F - 32) × 5/9.
Understanding the Conversion Formula
The formula to convert Fahrenheit to Celsius involves subtracting 32 from the Fahrenheit temperature to adjust for the difference in zero points between the two scales, and then multiplying by 5⁄9, which is the ratio of the intervals between units in the two scales. Applying this formula to 47 degrees Fahrenheit gives us: °C = (47 - 32) × 5⁄9.
Performing the Calculation
Subtracting 32 from 47 gives us 15. Then, multiplying 15 by 5 gives 75. Finally, dividing 75 by 9 gives us 8.333… Since the conversion involves a division that does not result in a whole number, we can round the result to a practical number of decimal places for most applications.
| Temperature in Fahrenheit | Temperature in Celsius |
|---|---|
| 47°F | 8.33°C (rounded to two decimal places) |
In scientific research or where precision is crucial, retaining more decimal places may be necessary. However, for general purposes, rounding to one or two decimal places is usually sufficient. Understanding the relationship between Fahrenheit and Celsius is essential for a wide range of activities, from monitoring weather patterns to conducting laboratory experiments.
Key Concepts in Temperature Conversion
Besides the formula, it’s helpful to remember key conversion points, such as the freezing point of water (32°F = 0°C) and the boiling point of water (212°F = 100°C), which can serve as reference points for mental calculations or estimates. Additionally, recognizing that an increase of 1.8°F is equivalent to an increase of 1°C can be useful for quick conversions in everyday situations.
