How to Convert Foot pound-force/second to Nanowatt

Converting Foot pound-force/second (ft·lbf/s) to Nanowatt (nW) 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/second equals 1.355818 × 10⁹ Nanowatt, while 1 nW equals 7.375621 × 10⁻¹⁰ 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:

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 ft·lbf/s = 1.355818 watt (W)
2. Target SI Bridge (ktarget):1 nW = 1 × 10⁻⁹ watt (W)
Step-by-step substitution for Foot pound-force/second → Nanowatt:V(nW) = V(ft·lbf/s) × ( 1.355818 / 1 × 10⁻⁹ ) = V(ft·lbf/s) × 1.355818 × 10⁹
Mathematical FormulaValue in Nanowatt = Value in Foot pound-force/second × 1.35581795 × 10⁹Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 36 ft·lbf/s, applying the conversion factor yields exactly 4.880945 × 10¹⁰ nW. At larger operational scale, 100 Foot pound-force/second corresponds to 1.355818 × 10¹¹ nW.

Inverse check: 1 nW = 7.375621 × 10⁻¹⁰ ft·lbf/s.

To perform the reverse calculation from nanowatts back to foot pound forces/second, you must divide your starting value by 1.35581795 × 10⁹. Our bidirectional tool automatically computes this inverse equation the moment you type into the nanowatt input field.

1 Foot pound-force/second is larger than 1 Nanowatt. Specifically, 1 Foot pound-force/second equals exactly 1.35581795 × 10⁹ nanowatts, making it 1.3558 × 10⁹ times larger (a difference of 9.13 orders of magnitude). Therefore, quantities expressed in nanowatts require a larger numerical value to represent the same physical amount.

A typical james Watt mechanical horsepower definition benchmark (550 ft·lbf/s = 1 hp) measures 550 ft·lbf/s, which corresponds to 7.457 × 10¹¹ Nanowatt (Nanowatt).

There are exactly 1.35582 × 10⁹ Nanowatts (nW) in 1 Foot pound-force/second (ft·lbf/s). The formula is: 1 ft·lbf/s = 1.35582 × 10⁹ nW.

To convert a power value from Foot pound-force/second to Nanowatt, multiply the value in ft·lbf/s by 1.35582 × 10⁹. The KaTeX equation is: V(nW) = V(ft·lbf/s) × 1.35582 × 10⁹.
