About Converting Quettawatts to Foot-pounds per second
Quettawatt and Foot-pound per second 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: Quettawatt is 1e+30 watt units, and mechanical power rate.
Formula
foot-pounds per second = quettawatts × 7.375621e+29
This factor comes from each unit's defined relationship to the category's base unit: 1 quettawatt equals 1e+30 base units, and 1 foot-pound per second equals 1.35581794833 base units, so dividing one by the other gives the direct quettawatt-to-foot-pound per second factor of 7.375621e+29.
Simple example
1 QW × 7.375621e+29 = 7.375621e+29 ft-lb/s
1 quettawatt = 7.375621e+29 foot-pounds per second.
Real-world example
100 QW × 7.375621e+29 = 7.375621e+31 ft-lb/s
100 quettawatts = 7.375621e+31 foot-pounds per second.

Frequently asked questions
How many foot-pounds per second are in 1 quettawatt?
1 quettawatt equals 7.375621e+29 foot-pounds per second, using the exact defined conversion factor rather than an estimate.
How do I convert quettawatt to foot-pound per second?
Multiply the quettawatt value by 7.375621e+29. The converter above does this instantly to whatever precision you set.
How do I convert foot-pound per second back to quettawatt?
Use the reverse factor: 1 foot-pound per second equals 1.355818e-30 quettawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a quettawatt?
Quettawatt (QW) is a unit of engineering.
What is a foot-pound per second?
Foot-pound per second (ft-lb/s) is a unit of engineering.
Is the quettawatt to foot-pound per second conversion exact?
Yes. Both quettawatt and foot-pound per second are defined by fixed standards rather than physical artifacts, so the factor of 7.375621e+29 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.
