Question 1

What is thermal conductivity and how is it measured?

Accepted Answer

Thermal conductivity (W/m·K) measures how well a material conducts heat. Higher values mean better heat transfer. Metals are typically 50-400 W/m·K.

Question 2

How do I convert thermal property units?

Accepted Answer

Enter your value and the converter calculates equivalents. Thermal units include conductivity (W/m·K), resistance (m²·K/W), and R-values.

Question 3

What is R-value and U-value?

Accepted Answer

R-value measures thermal resistance (higher = better insulation). U-value is thermal transmittance (lower = better insulation). U = 1/R.

Question 4

When are thermal calculations needed?

Accepted Answer

Thermal calculations are essential for building insulation, HVAC design, heat exchanger sizing, and thermal management in electronics.
