About Converting Foot-pounds per second to Nanowatts
Foot-pound per second and Nanowatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Mechanical power rate, and nanowatt is 1e-9 watt units.
Formula
nanowatts = foot-pounds per second × 1355817948.33
This factor comes from each unit's defined relationship to the category's base unit: 1 foot-pound per second equals 1.35581794833 base units, and 1 nanowatt equals 1e-9 base units, so dividing one by the other gives the direct foot-pound per second-to-nanowatt factor of 1355817948.33.
Simple example
1 ft-lb/s × 1355817948 = 1,355,817,948 nW
1 foot-pound per second = 1,355,817,948 nanowatts.
Real-world example
100 ft-lb/s × 1355817948 = 135,581,794,800 nW
100 foot-pounds per second = 135,581,794,800 nanowatts.

Reverse conversion: Nanowatt to Foot-pound per second
1 nW × 7.375621e-10 = 7.375621e-10 ft-lb/s
1 nanowatt = 7.375621e-10 foot-pounds per second.
foot-pounds per second = nanowatts × 7.375621e-10

Frequently asked questions
How many nanowatts are in 1 foot-pound per second?
1 foot-pound per second equals 1,355,817,948 nanowatts, using the exact defined conversion factor rather than an estimate.
How do I convert foot-pound per second to nanowatt?
Multiply the foot-pound per second value by 1355817948. The converter above does this instantly to whatever precision you set.
How do I convert nanowatt back to foot-pound per second?
Use the reverse factor: 1 nanowatt equals 7.375621e-10 foot-pounds per second. You can also use the swap control in the converter above to flip the direction instantly.
What is a foot-pound per second?
Foot-pound per second (ft-lb/s) is a unit of engineering.
What is a nanowatt?
Nanowatt (nW) is a unit of engineering.
Is the foot-pound per second to nanowatt conversion exact?
Yes. Both foot-pound per second and nanowatt are defined by fixed standards rather than physical artifacts, so the factor of 1355817948 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
