How to Convert Kilocalorie (th)/kilogram/°C to CHU/pound/°C

Converting Kilocalorie (th)/kilogram/°C (kcal (th)/(kg·°C)) to CHU/pound/°C (CHU/(lb·°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 Kilocalorie (th)/kilogram/°C equals 0.999331 CHU/pound/°C, while 1 CHU/(lb·°C) equals 1.00067 kcal (th)/(kg·°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:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 kcal (th)/(kg·°C) = 4183.995381 joule per kilogram kelvin (J/(kg·K))
2. Target SI Bridge (ktarget):1 CHU/(lb·°C) = 4186.798188 joule per kilogram kelvin (J/(kg·K))
Step-by-step substitution for Kilocalorie (th)/kilogram/°C → CHU/pound/°C:V(CHU/(lb·°C)) = V(kcal (th)/(kg·°C)) × ( 4183.995381 / 4186.798188 ) = V(kcal (th)/(kg·°C)) × 0.999331
