How to Convert CHU/cubic foot to Btu (IT)/gallon (UK)

Converting CHU/cubic foot (CHU/ft³) to Btu (IT)/gallon (UK) (Btu/gal (UK)) 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 0.288991 Btu (IT)/gallon (UK), while 1 Btu/gal (UK) equals 3.460312 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)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 CHU/ft³ = 67069.081154 joule per cubic meter (J/m³)
2. Target SI Bridge (ktarget):1 Btu/gal (UK) = 232079.9469 joule per cubic meter (J/m³)
Step-by-step substitution for CHU/cubic foot → Btu (IT)/gallon (UK):V(Btu/gal (UK)) = V(CHU/ft³) × ( 67069.081154 / 232079.9469 ) = V(CHU/ft³) × 0.288991
Mathematical FormulaValue in Btu (IT)/gallon (UK) = Value in CHU/cubic foot × 0.28899128Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 15 CHU/ft³, applying the conversion factor yields exactly 4.334869 Btu/gal (UK). At larger operational scale, 240 CHU/cubic foot corresponds to 69.357907 Btu/gal (UK).
