How to Convert Foot pound-force/hour to Foot pound-force/second

Converting Foot pound-force/hour (ft·lbf/h) to Foot pound-force/second (ft·lbf/s) 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-force/hour equals 0.000277778 Foot pound-force/second, while 1 ft·lbf/s equals 3600 ft·lbf/h.

Direct Factor1 ft·lbf/h = 0.000277778 ft·lbf/s

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/h = 0.000376616 watt (W)

2. Target SI Bridge (k_target):1 ft·lbf/s = 1.355818 watt (W)

Step-by-step substitution for Foot pound-force/hour → Foot pound-force/second:V(ft·lbf/s) = V(ft·lbf/h) × ( 0.000376616 / 1.355818 ) = V(ft·lbf/h) × 0.000277778

Mathematical FormulaValue in Foot pound-force/second = Value in Foot pound-force/hour × 0.00027777778Direct computational formula applied for standard conversion.

Worked Example

To convert 24 Foot pound-force/hour (ft·lbf/h) to Foot pound-force/second (ft·lbf/s): multiply 24 by 0.000277778 to get 0.00666667 ft·lbf/s. At an industrial engineering scale, 5000 ft·lbf/h converts to 1.388889 ft·lbf/s.

Inverse check: 1 ft·lbf/s = 3600 ft·lbf/h.
