How to Convert Square Metre Hour Degree Celsius per Kilocalorie to RSI (m²·K/W)
- 1 m²·h·°C/kcal = 0.8598452279 m²·K/W
- 1 m²·K/W = 1.163 m²·h·°C/kcal
- Example: convert 15 m²·h·°C/kcal to m²·K/W: 15 m²·h·°C/kcal = 15 × 0.8598452279 m²·K/W = 12.89767842 m²·K/W
Reference conditions. m²·h·°C/kcal: International Table kilocalorie (4186.8 J).
Formula
m²·K/W = m²·h·°C/kcal × 0.859845227859
or m²·K/W = m²·h·°C/kcal ÷ 1.163
Derivation from SI units:
- 1 m²·h·°C/kcal_IT = 3600 s ÷ 4186.8 J × m²·K ≈ 0.85985 m²·K/W.
- Thermal resistance per unit area R = thickness ÷ conductivity, in m²·K/W; U = 1/ΣR.
Both units are defined exactly, so the factor is exact. Square Metre Hour Degree Celsius per Kilocalorie definition: square metre hour degree Celsius per kilocalorie; RSI (m²·K/W) definition: square metre kelvin per watt.
Worked examples
- A reading of 1.5 m²·h·°C/kcal converts to 1.289767842 m²·K/W.
1.5 m²·h·°C/kcal × 0.8598452279 = 1.289767842 m²·K/W - A value of 3 m²·h·°C/kcal is 2.579535684 m²·K/W.
3 m²·h·°C/kcal × 0.8598452279 = 2.579535684 m²·K/W

Where it's used
Square Metre Hour Degree Celsius per Kilocalorie are used for older building-physics texts and IS codes, while square metre kelvin per watt appear in building envelope design (ECBC, Part L, EN ISO 6946). Both measure thermal resistance per unit area (insulation R-value), so the conversion is a fixed factor.
