In-lb to In-oz
The in-lb to in-oz Formula
To convert a larger torque unit (inch-pounds) to a smaller, more sensitive unit (inch-ounces), you multiply the value by 16.
Formula:
Example: If a precision screw requires 2.5 in-lb of torque, but your torque screwdriver only reads in ounces:
Inch-Pounds to Inch-Ounces Reference Table
| Inch-Pounds (in-lb) | Inch-Ounces (in-oz) | Common Application |
| 0.5 in-lb | 8 in-oz | Micro-electronics / Optical tools |
| 1.0 in-lb | 16 in-oz | Small Circuit Board Mounts |
| 2.0 in-lb | 32 in-oz | Computer Hard Drive Assembly |
| 5.0 in-lb | 80 in-oz | RC Hobbyist Servos |
| 10.0 in-lb | 160 in-oz | Bicycle Stem/Handlebar Bolts |
| 15.0 in-lb | 240 in-oz | Plastic Housing Fasteners |
When to Use in-oz Instead of in-lb
While automotive mechanics typically work in Foot-Pounds (ft-lb) or Inch-Pounds (in-lb), specialists in high-tech fields require finer resolution.
- Robotics: Small stepper motors often provide torque ratings in in-oz or oz-in.
- Aerospace: Delicate instrumentation requires torque so light that inch-pounds would result in difficult-to-read decimals.
- RC Modeling: Servos are almost exclusively rated in inch-ounces to denote their holding power.
Frequently Asked Questions
How do I convert 10 inch-pounds to inch-ounces?
Simply multiply 10 by 16. The result is 160 in-oz.
Is oz-in the same as in-oz?
Yes. In torque measurement, the order of the units (Ounce-Inch or Inch-Ounce) does not change the value. Both represent force multiplied by distance.
Can I use this for metric conversions?
This tool is for Imperial units. If you need to convert to metric, you would need to convert to Newton-Meters (Nm) or centi-Newton-Meters (cNm).
What is 2 in-lb in in-oz?
To find the answer, you multiply the inch-pounds by the conversion factor of 16.
2 in-lb is equal to 32 in-oz.
Is 1 in-lb the same as 8 in-oz?
No. 1 in-lb is actually equal to 16 in-oz.
