The conversion of 2 o to psia results in approximately 0.000568 psia.
This is because 1 o (ounce-force) is equal to about 0.0002846 pounds-force (lbf). To convert ounces-force to pounds-force, divide by 16. Since 1 psi equals 1 lbf per square inch, dividing the force in pounds-force by the area in square inches gives the pressure in psi, which is then converted to psia by considering atmospheric pressure if needed.

Conversion Formula
The formula to convert o to psia involves multiplying the value in o by 0.0002846. This works because 1 o equals 0.0002846 pounds-force, and since psi is pounds-force per square inch, directly multiplying gives the pressure in psi. For example, 2 o times 0.0002846 equals 0.0005692 psia.
Conversion Example
- Convert 5 o to psia:
- Multiply 5 by 0.0002846:
- 5 * 0.0002846 = 0.001423 psia
- Thus, 5 o equals approximately 0.001423 psia.
- Convert 10 o to psia:
- 10 * 0.0002846 = 0.002846 psia
- So, 10 o equals roughly 0.002846 psia.
- Convert 0.5 o to psia:
- 0.5 * 0.0002846 = 0.0001423 psia
- Therefore, 0.5 o equals about 0.0001423 psia.

Conversion Definitions
“o” is a unit measuring force, specifically ounces-force, representing the force exerted by a one-ounce mass under Earth’s gravity. It is used in measuring small forces in engineering contexts, often in calibration and precise force measurements.
“psia” stands for pounds per square inch absolute, representing pressure measured relative to a perfect vacuum. It accounts for atmospheric pressure, indicating the total pressure exerted on a surface including atmospheric contributions.
Conversion FAQs
How accurate is the conversion from o to psia?
The conversion uses a fixed factor of 0.0002846, which is precise for standard gravity and unit definitions. Minor variations can occur based on local gravity differences or measurement methods, but generally, it provides reliable estimates.
Why is it necessary to convert o to psia?
Converting o to psia helps when translating force measurements into pressure readings, especially in engineering, physics, or calibration tasks where pressure units are needed for system analysis or safety calculations.
Can I use this conversion for larger forces in ounces-force?
No, the formula is designed for small force values like 2 o. For larger forces, the conversion remains valid mathematically, but practical measurement methods might change, and calibration may be necessary. Always verify units and measurement context.
Does atmospheric pressure need to be added after conversion?
If you are seeking gauge pressure, then yes, atmospheric pressure must be added to the psia value. The conversion provides absolute pressure, including atmospheric pressure, so subtracting atmospheric pressure yields gauge pressure if needed.
