How to Convert CHU/pound/°C to Joule/gram/°C

Converting CHU/pound/°C (CHU/(lb·°C)) to Joule/gram/°C (J/(g·°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 4.186798 Joule/gram/°C, while 1 J/(g·°C) equals 0.238846 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)

2. Target SI Bridge (ktarget):1 J/(g·°C) = 1000 joule per kilogram kelvin (J/(kg·K))
Step-by-step substitution for CHU/pound/°C → Joule/gram/°C:V(J/(g·°C)) = V(CHU/(lb·°C)) × ( 4186.798188 / 1000 ) = V(CHU/(lb·°C)) × 4.186798

Worked Example

For an engineering input of 75 CHU/(lb·°C), applying the conversion factor yields exactly 314.009864 J/(g·°C). At larger operational scale, 10000 CHU/pound/°C corresponds to 41867.98188 J/(g·°C).

Inverse check: 1 J/(g·°C) = 0.238846 CHU/(lb·°C).
