In today’s digitally driven world, converting complex thermal conductivity units has never been easier. Whether you’re an engineer, HVAC professional, scientist, or student, understanding how to convert BTU (th)/inch/hour/sq. ft/°F to kcal/hr/m/°C is essential when working with different international systems of measurement. Luckily, you no longer need to perform these calculations manually — an online calculator can save you both time and headaches.
This article provides a comprehensive guide to this conversion, complete with an easy-to-use online calculator, a step-by-step conversion process, and explanations of what each unit means. Let’s dive in!
📌 Understanding the Units
Before jumping into the calculator, it’s essential to understand what you’re converting.
🔹 What is BTU (th)/inch/hour/sq. ft/°F?
- BTU (th): Stands for British Thermal Unit (thermochemical), a unit of energy.
- Inch: Refers to the material thickness.
- Hour: Time factor.
- Sq. Ft: Surface area.
- °F: Temperature difference in Fahrenheit.
This compound unit measures thermal conductivity — how well heat is transferred through a material.
🔹 What is kcal/hr/m/°C?
- kcal: Kilocalorie — a metric unit of energy.
- hr: Hour.
- m: Meter (length).
- °C: Temperature difference in Celsius.
This is the metric equivalent for measuring thermal conductivity.
🔁 Conversion Formula: How to Convert BTU (th)/Inch/Hour/Sq. Ft/°F to Kcal/hr/m/°C
To convert BTU (th)/inch/hour/sq. ft/°F to kcal/hr/m/°C, use the following standard conversion factor:
1 BTU (th)/in/hr/ft²/°F = 1.730735 kcal/hr/m/°C
✅ Formula:

📚 Conversion Example: Manual Calculation
Let’s walk through a practical example.
Problem:
Convert 5 BTU (th)/in/hr/ft²/°F to kcal/hr/m/°C.
Step-by-Step:
- Identify the conversion factor:
- 1 BTU (th)/in/hr/ft²/°F = 1.730735 kcal/hr/m/°C
- Apply the formula:
5 × 1.730735 = 8.653675 kcal/hr/m/°C
✅ Final Answer:
5 BTU (th)/in/hr/ft²/°F = 8.653675 kcal/hr/m/°C
📈 Why This Conversion Matters
Thermal conductivity plays a crucial role in:
- Building insulation design
- Heat exchanger efficiency
- Engineering material analysis
- HVAC system planning
Switching between imperial and metric systems ensures international compatibility and accurate thermal calculations across global projects.
🧠 Tips for Accurate Conversion
- Always ensure unit consistency (e.g., check thickness is in inches and temperature in Fahrenheit before converting).
- Use the online calculator for quick results, especially when handling large data sets.
- For reverse conversion, divide the value in kcal/hr/m/°C by the conversion factor.
Reverse Formula:
