Temperature is a measure of the hotness or coldness of a substance. Two widely used temperature scales are Celsius and Fahrenheit. The Celsius scale is commonly used in most countries, while the Fahrenheit scale is primarily used in the United States and a few other countries.
The formula for converting Celsius to Fahrenheit is:
°F = (°C × 9/5) + 32
Where:
Using the formula above, we can convert 48°C to Fahrenheit as follows:
°F = (48°C × 9/5) + 32
°F = (86.4) + 32
°F = 119.2
Therefore, 48°C is equal to 119.2°F.
Celsius (°C) | Fahrenheit (°F) |
---|---|
0 | 32 |
10 | 50 |
20 | 68 |
30 | 86 |
40 | 104 |
Converting temperature accurately is important for various reasons:
Converting temperature to the desired scale provides several benefits:
Step 1: Multiply the Celsius temperature by 9/5.
48°C × 9/5 = 86.4
Step 2: Add 32 to the result.
86.4 + 32 = 119.2°F
Therefore, 48°C is equal to 119.2°F.
Story 1:
A scientist working on a temperature-sensitive experiment accidentally records a temperature in Fahrenheit instead of Celsius. The scientist realizes the error and quickly converts the temperature to Celsius using the formula, ensuring accurate data analysis.
Lesson: Accurate temperature conversion is crucial for scientific research to prevent erroneous conclusions.
Story 2:
A chef follows a recipe that specifies a cooking temperature in Fahrenheit. The chef converts the temperature to Celsius using a conversion table, ensuring that the dish is cooked to the correct temperature.
Lesson: Converting temperature is essential for successful cooking and baking to achieve consistent results.
Story 3:
A traveler visiting a country with a different temperature scale experiences difficulty understanding local weather reports. The traveler learns to convert temperatures between Celsius and Fahrenheit, enabling them to plan activities and dress appropriately.
Lesson: Temperature conversion is valuable for travelers to enhance situational awareness and adapt to different climates.
1. How do I convert 25°C to Fahrenheit?
°F = (25°C × 9/5) + 32 = 77°F
2. Is there a quick way to estimate the Fahrenheit temperature for a Celsius temperature?
Double the Celsius temperature and add 30. This provides an approximate Fahrenheit value.
3. Why are different temperature scales used around the world?
Historically, different countries and regions developed their own temperature scales. Celsius is based on the freezing and boiling points of water, while Fahrenheit is based on a mercury thermometer.
4. Is it recommended to use a calculator for accurate temperature conversions?
While calculators provide precise conversions, using the formula or a conversion table is sufficient for most practical applications.
5. What is 100°C in Fahrenheit?
100°C is equal to 212°F.
6. What is 0°F in Celsius?
0°F is equal to -17.8°C.
Converting temperatures between Celsius and Fahrenheit is a common and essential task for various scientific, everyday, and practical applications. Understanding the formula and using conversion tools allows individuals to accurately convert temperatures, fostering wider understanding, enhanced communication, and improved safety.
