Fundamentals

Stress is a basic physical quantity for measuring the relevant object; unit conversion unifies dimensions across standards, drawings and test data.

This tool uses Pascal (Pa) as the base unit and scales the input by each unit's factor to the target; temperature and similar quantities use affine conversion $y=a x+b$. All factors are relative to SI.

History

Measurement of Stress has a long history: ancient standards used body parts (cubit, foot) or nature (sundials, water clocks); the metric system (1790s) and SI (1960) unified global measurement.

Engineering applications

In mechanical design, trade, international drawings and test data, Stress must often be converted between customary units such as Pascal (Pa) and SI to keep dimensions consistent.

Glossary

Base unitReference unit, usually SI (e.g. Pascal (Pa)).
Conversion factorProportional factor between a unit and the base.
Linear / affineMost units are linear; temperature needs an offset (affine).

Formula

This tool uses Pascal (Pa) as the base unit and scales the input by each unit's factor; all but temperature are proportional.

Worked Example

From Pascal (Pa) to kPa: result = value ×(src factor / tgt factor); use ⇅ to reverse.
