What does pound-force per square inch measure?

It measures pressure as one pound-force applied over an area of one square inch, commonly used in engineering contexts like automotive and hydraulic systems.

What is the microbar used for?

The microbar is used to measure very small pressures, such as those found in vacuum systems, sensitive atmospheric monitoring, and space simulation environments.

Why are conversion results from psi to microbar very large?

Because pound-force per square inch measures higher pressures and microbar measures extremely low pressures, the numerical conversion results in very large values.

Tips & Best Practices

Use this converter when needing to express common high-pressure measurements in units suitable for very low pressures.
Double-check unit selections before conversion to ensure accuracy.
Apply converted values carefully in contexts requiring sensitivity to pressure range differences.
Consider instrument sensitivity limits when interpreting large converted values.

Limitations

Pound-force per square inch is designed for relatively high-pressure ranges, while microbar measures very low pressures.
Conversions often yield very large numerical results due to differing unit scales.
These large values may be impractical for routine measurements at low pressures.
Accuracy can be affected by the sensitivity limits of measuring instruments in each pressure scale.
