How to Convert CHU/pound/°C to Kilocalorie (th)/kilogram/°C
Converting CHU/pound/°C (CHU/(lb·°C)) to Kilocalorie (th)/kilogram/°C (kcal (th)/(kg·°C)) is a core calculation in Specific Heat Capacity, which measures the thermal energy required to raise the temperature of a unit mass of substance by one degree. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 CHU/pound/°C equals 1.00067 Kilocalorie (th)/kilogram/°C, while 1 kcal (th)/(kg·°C) equals 0.999331 CHU/(lb·°C).
Mathematical Conversion Derivation via Coherent SI Base Unit
Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (joule per kilogram kelvin (J/(kg·K))) without arbitrary rounding:
1 CHU/(lb·°C) = 4186.798188 joule per kilogram kelvin (J/(kg·K))1 kcal (th)/(kg·°C) = 4183.995381 joule per kilogram kelvin (J/(kg·K))V(kcal (th)/(kg·°C)) = V(CHU/(lb·°C)) × ( 4186.798188 / 4183.995381 ) = V(CHU/(lb·°C)) × 1.00067Value in Kilocalorie (th)/kilogram/°C = Value in CHU/pound/°C × 1.00066989Direct computational formula applied for standard conversion.For an engineering input of 36 CHU/(lb·°C), applying the conversion factor yields exactly 36.024116 kcal (th)/(kg·°C). At larger operational scale, 5000 CHU/pound/°C corresponds to 5003.349439 kcal (th)/(kg·°C).
Inverse check: 1 kcal (th)/(kg·°C) = 0.999331 CHU/(lb·°C).Understanding CHU/pound/°C and Kilocalorie (th)/kilogram/°C
