How to Convert Temperatures by Hand
Converting temperatures between different units can be done using specific formulas. Here’s a detailed guide:
Step-by-Step Guide
1. To convert from Celsius to Fahrenheit, use the formula:
F = (C × 9/5) + 32
For example, to convert 25°C to Fahrenheit:
F = (25 × 9/5) + 32 = 77°F
2. To convert from Fahrenheit to Celsius, use the formula:
C = (F - 32) × 5/9
For example, to convert 77°F to Celsius:
C = (77 - 32) × 5/9 = 25°C
3. To convert from Celsius to Kelvin, use the formula:
K = C + 273.15
For example, to convert 25°C to Kelvin:
K = 25 + 273.15 = 298.15K
4. To convert from Kelvin to Celsius, use the formula:
C = K - 273.15
For example, to convert 298.15K to Celsius:
C = 298.15 - 273.15 = 25°C
Example Calculation
Let’s say you want to convert 25°C to Fahrenheit and Kelvin:
1. Convert 25°C to Fahrenheit:
F = (25 × 9/5) + 32 = 77°F
2. Convert 25°C to Kelvin:
K = 25 + 273.15 = 298.15K
Conclusion
By following these steps, you can manually convert temperatures between Celsius, Fahrenheit, and Kelvin. Understanding these conversions can be helpful in various scientific and everyday contexts.
