About Converting Pound-inches to Yottanewton meters
Pound-inch and Yottanewton meter 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: Torque from one pound-force at one inch, and yottanewton meter is 1e+24 newton meter units.
Formula
yottanewton meters = pound-inches × 1.129848e-25
This factor comes from each unit's defined relationship to the category's base unit: 1 pound-inch equals 0.112984829028 base units, and 1 yottanewton meter equals 1e+24 base units, so dividing one by the other gives the direct pound-inch-to-yottanewton meter factor of 1.129848e-25.
Simple example
1 lb in × 1.129848e-25 = 1.129848e-25 YN m
1 pound-inch = 1.129848e-25 yottanewton meters.
Real-world example
100 lb in × 1.129848e-25 = 1.129848e-23 YN m
100 pound-inches = 1.129848e-23 yottanewton meters.

What is a pound-inch?
Pound-inch (lb in) is a unit of engineering.
What is a yottanewton meter?
Yottanewton meter (YN m) is a unit of engineering.
Is the pound-inch to yottanewton meter conversion exact?
Yes. Both pound-inch and yottanewton meter are defined by fixed standards rather than physical artifacts, so the factor of 1.129848e-25 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.
