How to Convert CHU/cubic foot to Therm/cubic foot

Converting CHU/cubic foot (CHU/ft³) to Therm/cubic foot (therm/ft³) is a core calculation in Volumetric Energy Density, which quantifies the energetic output yield released per unit volume of fuel. 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/cubic foot equals 1.799997 × 10⁻⁵ Therm/cubic foot, while 1 therm/ft³ equals 55555.642203 CHU/ft³.

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 cubic meter (J/m³)) 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)

1. Source SI Bridge (ksource):1 CHU/ft³ = 67066 joule per cubic meter (J/m³)
2. Target SI Bridge (ktarget):1 therm/ft³ = 3.725895 × 10⁹ joule per cubic meter (J/m³)
Step-by-step substitution for CHU/cubic foot → Therm/cubic foot:V(therm/ft³) = V(CHU/ft³) × ( 67066 / 3.725895 × 10⁹ ) = V(CHU/ft³) × 1.799997 × 10⁻⁵
