Users should carefully consider the differences in temperature scales and area units involved to avoid calculation errors.

Key Terminology

Btu (IT)/hour/square foot/°F
An imperial unit measuring heat flow per hour through one square foot area per degree Fahrenheit temperature difference; known as the U-value.
Joule/second/square meter/K
A metric heat transfer coefficient unit signifying heat flow rate per square meter area per Kelvin temperature difference (equivalently watts per square meter per kelvin).
Heat Transfer Coefficient
A measure quantifying the rate at which heat passes through a surface or material per unit area and per temperature difference.
