About Converting Ounce-inches to Pound-inches
Ounce-inch and Pound-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 ounce-force at one inch, and torque from one pound-force at one inch.
Formula
pound-inches = ounce-inches × 0.0625
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce-inch equals 0.00706155181423 base units, and 1 pound-inch equals 0.112984829028 base units, so dividing one by the other gives the direct ounce-inch-to-pound-inch factor of 0.0625.
Simple example
1 oz in × 0.0625 = 0.0625 lb in
1 ounce-inch = 0.0625 pound-inches.
Real-world example
100 oz in × 0.0625 = 6.25 lb in
100 ounce-inches = 6.25 pound-inches.

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