How to Convert in-oz to in-lb: Step by Step
To convert small torque values (in-oz) to larger units (in-lb), you simply divide the value by 16.
The Formula:
in−lb=in−oz÷16
Example Calculation:
If your servo motor is rated at 48 in-oz, what is that in inch-pounds?
48÷16=3.0 in-lb

Frequently Asked Questions
1. How many inch-ounces are in an inch-pound?
There are exactly 16 inch-ounces in 1 inch-pound.
2. Is an inch-pound the same as a foot-pound?
No. An inch-pound measures force applied over one inch, while a foot-pound (ft-lb) measures force over one foot. To convert in-lb to ft-lb, you would divide by 12.
3. When should I use in-oz instead of in-lb?
Use in-oz for very low-torque applications where using inch-pounds would result in very small fractions (e.g., 0.125 in-lb is much easier to read as 2 in-oz).
4. Can this calculator convert in-lb back to in-oz?
Yes! To go backward, simply multiply your inch-pounds by 16. Our tool handles both directions effortlessly.
