About Converting Foot-pounds per second to Gigawatts
Foot-pound per second and Gigawatt 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 gigawatt is 1000000000 watt units.
Formula
gigawatts = foot-pounds per second × 1.355818e-9
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 gigawatt equals 1000000000 base units, so dividing one by the other gives the direct foot-pound per second-to-gigawatt factor of 1.355818e-9.
Simple example
1 ft-lb/s × 1.355818e-9 = 1.355818e-9 GW
1 foot-pound per second = 1.355818e-9 gigawatts.
Real-world example
100 ft-lb/s × 1.355818e-9 = 1.355818e-7 GW
100 foot-pounds per second = 1.355818e-7 gigawatts.

Frequently asked questions
How many gigawatts are in 1 foot-pound per second?
1 foot-pound per second equals 1.355818e-9 gigawatts, using the exact defined conversion factor rather than an estimate.
How do I convert foot-pound per second to gigawatt?
Multiply the foot-pound per second value by 1.355818e-9. The converter above does this instantly to whatever precision you set.
How do I convert gigawatt back to foot-pound per second?
Use the reverse factor: 1 gigawatt equals 737,562,149.3 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 gigawatt?
Gigawatt (GW) is a unit of engineering.
Is the foot-pound per second to gigawatt conversion exact?
Yes. Both foot-pound per second and gigawatt are defined by fixed standards rather than physical artifacts, so the factor of 1.355818e-9 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.
