How to Convert Inch-pound to Btu (th)

Converting Inch-pound (in·lb) to Btu (th) (Btu (th)) is a core calculation in Energy and Work, which quantifies the physical capacity to perform mechanical work, generate heat, or emit electromagnetic radiation. 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 Inch-pound equals 0.000107161 Btu (th), while 1 Btu (th) equals 9331.786386 in·lb.

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 (J)) 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 in·lb = 0.112985 joule (J)
2. Target SI Bridge (ktarget):1 Btu (th) = 1054.350264 joule (J)
Step-by-step substitution for Inch-pound → Btu (th):V(Btu (th)) = V(in·lb) × ( 0.112985 / 1054.350264 ) = V(in·lb) × 0.000107161
Mathematical FormulaValue in Btu (th) = Value in Inch-pound × 0.00010716062Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 120 Inch-pound (in·lb) produces 0.0128593 Btu (th) (Btu (th)). In heavy-duty utility and industrial workloads, 2500 in·lb equals 0.267902 Btu (th).

Inverse check: 1 Btu (th) = 9331.786386 in·lb.
