About Converting Pound-inches to Ounce-inches
Pound-inch and Ounce-inch 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 torque from one ounce-force at one inch.
Formula
ounce-inches = pound-inches × 16
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 ounce-inch equals 0.00706155181423 base units, so dividing one by the other gives the direct pound-inch-to-ounce-inch factor of 16.
Simple example
1 lb in × 16 = 16 oz in
1 pound-inch = 16 ounce-inches.
Real-world example
100 lb in × 16 = 1,600 oz in
100 pound-inches = 1,600 ounce-inches.

Frequently asked questions
How many ounce-inches are in 1 pound-inch?
1 pound-inch equals 16 ounce-inches, using the exact defined conversion factor rather than an estimate.
How do I convert pound-inch to ounce-inch?
Multiply the pound-inch value by 16. The converter above does this instantly to whatever precision you set.
How do I convert ounce-inch back to pound-inch?
Use the reverse factor: 1 ounce-inch equals 0.0625 pound-inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound-inch?
Pound-inch (lb in) is a unit of engineering.
What is a ounce-inch?
Ounce-inch (oz in) is a unit of engineering.
Is the pound-inch to ounce-inch conversion exact?
Yes. Both pound-inch and ounce-inch are defined by fixed standards rather than physical artifacts, so the factor of 16 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.
