kcal/(h·m²·°C)
The kilocalorie per hour square metre degree Celsius is an older metric unit of heat transfer coefficient, exactly 1.163 W/(m²·K) with the International Table kilocalorie.
Symbol: kcal/(h·m²·°C) (ASCII: kcal/(h*m2*C))
Quantity: heat transfer coefficient (h) and thermal transmittance (U-value)
SI relation: 1 kcal/(h·m²·°C) = 1.163 W/(m²·K) (exact)
Derivation: 1 kcal_IT/(h·m²·°C) = 4186.8 J ÷ (3600 s × 1 m² × 1 K) = 1.163 W/(m²·K) (exact)
Exact: yes, by definition
Reference conditions. International Table kilocalorie (4186.8 J), as used in engineering heat transfer data
Typical uses
- Older metric heat exchanger and boiler data
- Asian and Russian engineering tables
