Konversi Skala Termometer (Celcius, Reamur, Fahrenheit, dan Kelvin)

Introduction

In this tutorial, we will explore how to convert temperatures between four commonly used scales: Celsius, Reamur, Fahrenheit, and Kelvin. Understanding these conversions is essential for various applications in science, cooking, and daily life. By the end of this guide, you'll be equipped with the formulas needed to perform these conversions easily.

Step 1: Understand the Temperature Scales

Before performing conversions, it's essential to know each temperature scale:

• Celsius (°C): A scale based on the freezing point of water (0°C) and the boiling point (100°C).
• Reamur (°R): A scale where water freezes at 0°R and boils at 80°R.
• Fahrenheit (°F): A scale where water freezes at 32°F and boils at 212°F.
• Kelvin (K): A scale starting from absolute zero, where 0 K is -273.15°C.

Step 2: Conversion Formulas

Familiarize yourself with the formulas for converting between the scales.

Celsius to Reamur

• Formula:

  °R = °C × 0.8
  

Celsius to Fahrenheit

• Formula:

  °F = (°C × 1.8) + 32
  

Celsius to Kelvin

• Formula:

  K = °C + 273.15
  

Reamur to Celsius

• Formula:

  °C = °R / 0.8
  

Fahrenheit to Celsius

• Formula:

  °C = (°F - 32) / 1.8
  

Kelvin to Celsius

• Formula:

  °C = K - 273.15
  

Step 3: Performing the Conversions

Follow these steps to convert temperatures:

1. Identify the initial temperature and scale.

   • Example: 25°C.

2. Choose the appropriate formula based on the target scale.

   • If converting from Celsius to Fahrenheit, use the Fahrenheit formula.

3. Plug the numbers into the formula and calculate.

   • For Celsius to Fahrenheit:

     °F = (25 × 1.8) + 32 = 77°F
     

4. Round your answer as necessary for practical use.

Step 4: Common Conversion Examples

Here are a few examples to illustrate the conversions:

• Convert 100°C to Reamur:

  °R = 100 × 0.8 = 80°R
  

• Convert 0°C to Kelvin:

  K = 0 + 273.15 = 273.15 K
  

• Convert 32°F to Celsius:

  °C = (32 - 32) / 1.8 = 0°C
  

Conclusion

By utilizing these formulas and steps, you can easily convert between Celsius, Reamur, Fahrenheit, and Kelvin. Practice with various temperatures to become proficient in these conversions. As you apply this knowledge, consider how temperature affects various scientific and everyday contexts, such as cooking and weather forecasting.
