How to Convert CHU/pound/°C to Calorie (th)/gram/K

Converting CHU/pound/°C (CHU/(lb·°C)) to Calorie (th)/gram/K (cal (th)/(g·K)) 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 Calorie (th)/gram/K, while 1 cal (th)/(g·K) 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:

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 CHU/(lb·°C) = 4186.798188 joule per kilogram kelvin (J/(kg·K))
2. Target SI Bridge (ktarget):1 cal (th)/(g·K) = 4183.995381 joule per kilogram kelvin (J/(kg·K))
Step-by-step substitution for CHU/pound/°C → Calorie (th)/gram/K:V(cal (th)/(g·K)) = V(CHU/(lb·°C)) × ( 4186.798188 / 4183.995381 ) = V(CHU/(lb·°C)) × 1.00067

Worked Example

Evaluating an input of 120 CHU/pound/°C (CHU/(lb·°C)) produces 120.080387 Calorie (th)/gram/K (cal (th)/(g·K)). In heavy-duty utility and industrial workloads, 100 CHU/(lb·°C) equals 100.066989 cal (th)/(g·K).
