Frequently Asked Questions
What is the difference between stress and strain?
Stress is the internal force per unit area within a material (force/area), while strain is the measure of deformation representing the displacement between particles in the material relative to a reference length (change in length/original length). Stress is typically measured in units like Pascal or PSI, while strain is dimensionless or expressed as a percentage.
Can I convert between stress and strain units with this tool?
No, this tool converts between different units of stress (e.g., Pa to PSI) or different units of strain (e.g., mm/mm to %), but not between stress and strain directly. Conversion between stress and strain requires knowledge of material properties such as Young’s modulus (E) according to Hooke’s Law: σ = E × ε.
How accurate are the conversions provided by this tool?
Our converter uses precise conversion factors based on international standards to ensure accuracy to at least 6 significant figures, which exceeds the requirements for most engineering applications. The tool automatically handles scientific notation for very large or very small values.
Which stress unit is most commonly used in engineering?
The most common stress units vary by region and engineering discipline. In many international standards and scientific contexts, Pascal (Pa) and its multiples (kPa, MPa, GPa) are used. In the US, pound-force per square inch (PSI) and kips per square inch (KSI) are common in structural engineering. Civil engineers often use N/mm² or MPa, while mechanical engineers might use bar or kg/cm² in certain applications.
How is microstrain related to regular strain?
Microstrain (μɛ) is simply strain multiplied by 10⁶ (one million). For example, a strain of 0.000123 is equivalent to 123 microstrain. Microstrain is commonly used in experimental stress analysis and strain gauge measurements because it provides more convenient numbers to work with when dealing with the typically small deformations in engineering materials.
Why do we need different units for stress in engineering?
Different units evolved in various engineering traditions and geographic regions. The variety of units allows engineers to work with numbers in convenient ranges for specific applications. For example, concrete strength might be expressed in MPa (megapascals), while soil bearing capacity might use kPa (kilopascals), and precision machining tolerances might use GPa (gigapascals) – all to avoid working with very large or very small numbers with many zeros.
