A heat transfer coefficient represents the amount of heat transferred per unit area per unit temperature difference. It's a measure of how effectively heat can be transferred between a surface and a fluid or between two surfaces.
Heat transfer coefficients represent the rate of heat transfer, which is always a positive quantity. The direction of heat flow is determined by the temperature difference, not the coefficient itself.
Typical values range from 0.1 W/m²·K for natural convection to 10,000+ W/m²·K for boiling water. Building materials typically range from 0.5 to 50 W/m²·K depending on the material and conditions.
Our converter uses precise conversion factors based on internationally recognized standards. All conversions maintain accuracy up to 8 decimal places for engineering and scientific applications.
