Are you trying to convert thermal conductivity units from Calorie (IT)/s/cm/°C to kW/m/K? Understanding how to move between these two units can be essential for scientists, engineers, and students working with heat transfer and thermal analysis. This guide walks you through the exact conversion process step-by-step and explains the principles behind it, ensuring complete clarity.
🔍 What Are These Units?
Before diving into the numbers, let’s break down what these two units represent.
✅ Calorie (IT)/s/cm/°C
This is a non-SI unit used to measure thermal conductivity. It describes how much heat (in International Table Calories) is conducted per second through a centimeter of material for each degree Celsius of temperature difference.
- Calorie (IT): An energy unit, approximately 4.1868 joules.
- s: Seconds.
- cm: Centimeters.
- °C: Degrees Celsius (same increment as Kelvin for differences in temperature).
✅ kW/m/K
This is the SI unit of thermal conductivity — kilowatt per meter per Kelvin. It tells us how many kilowatts of heat flow per meter of material for each Kelvin of temperature gradient.
💡 Conversion Formula
We want to convert:
0.6 Calorie (IT)/s/cm/°C → kW/m/K
🔁 Unit Conversion Steps
Let’s convert each part:
- Energy:
- 1 Calorie (IT) = 4.1868 joules
- Distance:
- 1 cm = 0.01 meters
- So per cm = ×100 when converting to per meter
- Temperature:
- Temperature difference in °C is equivalent to K (Kelvin), so no conversion needed here.
- Power:
- 1 watt = 1 joule/second
- 1 kilowatt = 1000 watts
🧮 Putting It All Together
Start with:
0.6 Cal (IT)/s/cm/°C
Step-by-Step Conversion:
Step 1: Convert calories to joules
= 0.6 × 4.1868 J/s/cm/°C
= 2.51208 J/s/cm/°C
Step 2: Convert per centimeter to per meter
Since 1 m = 100 cm, and we’re dealing with conductivity per length, we multiply by 100:
= 2.51208 × 100 = 251.208 J/s/m/°C
Step 3: Convert watts to kilowatts
251.208 J/s = 251.208 W = 0.251208 kW
Final Answer:
0.6 Calorie (IT)/s/cm/°C = 0.251208 kW/m/K
✅ Exact Answer
🧾 0.6 Calorie (IT)/s/cm/°C equals exactly 0.251208 kW/m/K
This is a precise scientific conversion, useful in technical applications like thermal insulation studies, HVAC design, material science, and energy modeling.
