kilocalorie per hour square meter Celsius
Heat transfer coefficientexact by definition
The kilocalorie per hour square meter Celsius is 4184/3600 = 1.162222222 W/(m²·K). It is the pre-SI European U-value unit, and its near-equality to 1 W/(m²·K) is a trap: a wall quoted as 1.0 in the old unit is 1.16 in the new one, a 16% error if the conversion is skipped.
