square meter Celsius per watt

Areal thermal resistanceexact by definition

The square meter Celsius per watt is exactly equal to RSI, the SI R-value, since a Celsius degree of difference is a kelvin. It is a label variant, not a different unit, and appears on European and Canadian product data interchangeably with m²·K/W.
