How to Convert Nanojoules to Foot-pounds
To convert nanojoules to foot-pounds, multiply the energy by the following conversion ratio: 7.375621e-10 foot-pounds/nanojoule.
Since one nanojoule is equal to 7.375621e-10 foot-pounds, you can use this simple formula to convert:
The energy in foot-pounds is equal to the energy in nanojoules multiplied by 7.375621e-10.
For example, here's how to convert 5 nanojoules to foot-pounds using the formula above.
How Many Foot-pounds Are in a Nanojoule?
There are 7.375621e-10 foot-pounds in a nanojoule, which is why we use this value in the formula above.

What Is a Nanojoule?
A nanojoule is a unit of energy equal to 1/1,000,000,000 of a joule (1e-9 J). One-billionth of a Joule. [1]
The nanojoule is classified as a metric and SI-compatible unit of energy. Nanojoules can be abbreviated as nJ; for example, 1 nanojoule can be written as 1 nJ.
In the metric system, "nano" is the standard SI prefix for billionths, or 10⁻⁹. This makes the nanojoule (nJ) a convenient decimal multiple of the joule (J).
In practice, nanojoules (nJ) are widely used across fine-tolerance laboratory, analytical, and micro-scale energy measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Foot-pound?
A foot-pound is a unit of energy equal to 1.3558179 joules (J), the base unit for energy. Mechanical work unit equal to 1.355818 Joules. [2]
The foot-pound is classified as a US customary and imperial unit of energy. Foot-pounds can be abbreviated as ft·lbf; for example, 1 foot-pound can be written as 1 ft·lbf.
When working with foot-pounds (ft·lbf) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, foot-pounds (ft·lbf) are widely used across standard energy applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
When converting energy between nanojoules (nJ) and foot-pounds (ft·lbf), keep full floating-point precision (1 nJ = 7.375621e-10 ft·lbf; 1 ft·lbf = 1,355,817,948.3314 nJ) during intermediate calculations and round only the final foot-pound figure to match your instrument tolerance.
