How to Convert Foot-pound/minute to Horsepower (mechanical)

Converting Foot-pound/minute (ft·lbf/min) to Horsepower (mechanical) (hp (I)) 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 Foot-pound/minute equals 3.030303 × 10⁻⁵ Horsepower (mechanical), while 1 hp (I) equals 32999.99999 ft·lbf/min.

Direct Factor1 ft·lbf/min = 3.030303 × 10⁻⁵ hp (I)

Inverse Ratio1 hp (I) = 32999.99999 ft·lbf/min

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 ft·lbf/min = 0.022597 watt (W)

2. Target SI Bridge (k_target):1 hp (I) = 745.699871 watt (W)

Step-by-step substitution for Foot-pound/minute → Horsepower (mechanical):V(hp (I)) = V(ft·lbf/min) × ( 0.022597 / 745.699871 ) = V(ft·lbf/min) × 3.030303 × 10⁻⁵

Mathematical FormulaValue in Horsepower (mechanical) = Value in Foot-pound/minute × 3.03030303 × 10⁻⁵Direct computational formula applied for standard conversion.

Worked Example

Evaluating an input of 120 Foot-pound/minute (ft·lbf/min) produces 0.00363636 Horsepower (mechanical) (hp (I)). In heavy-duty utility and industrial workloads, 2500 ft·lbf/min equals 0.0757576 hp (I).

Inverse check: 1 hp (I) = 32999.99999 ft·lbf/min.
