Temperature Conversion

What is Temperature Conversion?

Temperature conversion is the process of changing a temperature value from one scale to another. The most common temperature scales are Celsius (°C), Fahrenheit (°F), Kelvin (K), Rankine (°R), and Réaumur (°Ré).

Conversion Formulas

Here are the formulas for converting between different temperature scales:

• Celsius to Fahrenheit: \(F = C \times \frac{9}{5} + 32\)
• Fahrenheit to Celsius: \(C = (F - 32) \times \frac{5}{9}\)
• Celsius to Kelvin: \(K = C + 273.15\)
• Kelvin to Celsius: \(C = K - 273.15\)
• Celsius to Rankine: \(R = (C + 273.15) \times \frac{9}{5}\)
• Rankine to Celsius: \(C = (R - 491.67) \times \frac{5}{9}\)
• Celsius to Réaumur: \(Ré = C \times \frac{4}{5}\)
• Réaumur to Celsius: \(C = Ré \times \frac{5}{4}\)

Calculation Steps

1. Identify the initial temperature value and its scale.
2. Determine the desired temperature scale for conversion.
3. Apply the appropriate conversion formula.
4. Calculate the result and round to the desired precision.

Example Calculation

Let's convert 25°C to Fahrenheit:

1. Initial temperature: 25°C
2. Desired scale: Fahrenheit
3. Formula: \(F = C \times \frac{9}{5} + 32\)
4. Calculation: \(F = 25 \times \frac{9}{5} + 32 = 45 + 32 = 77\)
5. Result: 25°C = 77°F
