How to Convert Btu/hour to Foot-pound/minute

Converting Btu/hour (Btu/h) to Foot-pound/minute (ft·lbf/min) is a core calculation in Power, which measures the rate of energy expenditure, conversion, or work transfer per unit of time. 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 Btu/hour equals 12.969488 Foot-pound/minute, while 1 ft·lbf/min equals 0.077104 Btu/h.

First-Principles SI Derivation ProofNIST SP 811 / ISO 80000 Compliance

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 (watt (W)) without arbitrary rounding:

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 (k_source):1 Btu/h = 0.293071 watt (W)

2. Target SI Bridge (k_target):1 ft·lbf/min = 0.022597 watt (W)

Step-by-step substitution for Btu/hour → Foot-pound/minute:V(ft·lbf/min) = V(Btu/h) × ( 0.293071 / 0.022597 ) = V(Btu/h) × 12.969488

Mathematical FormulaValue in Foot-pound/minute = Value in Btu/hour × 12.96948772Direct computational formula applied for standard conversion.

Worked Example

For an engineering input of 250 Btu/h, applying the conversion factor yields exactly 3242.371929 ft·lbf/min. At larger operational scale, 2500 Btu/hour corresponds to 32423.719291 ft·lbf/min.

Inverse check: 1 ft·lbf/min = 0.077104 Btu/h.
