Pressure Units

  • Pascal (Pa) - SI unit, 1 Pa = 1 N/m²
  • Bar - 1 bar = 100,000 Pa
  • PSI - Pounds per square inch (Imperial)
  • Atmosphere (atm) - Standard atmospheric pressure

Force & Torque

  • Newton (N) - SI unit of force
  • Pound-force (lbf) - Imperial force unit
  • Newton-meter (N⋅m) - SI torque unit
  • Foot-pound (ft⋅lb) - Imperial torque
Engineering Applications
Where these conversions matter

Mechanical Engineering

Stress analysis, material selection, structural design, and machine component sizing require accurate unit conversions between metric and imperial systems.

Automotive & Aerospace

Engine torque specifications, tire pressure ratings, bolt tightening torques, and structural load calculations depend on precise unit conversions.

Civil Engineering

Concrete strength (MPa/psi), soil bearing capacity, wind loads, and structural stress calculations require conversions between different unit systems.

Engineering Conversion Tips

Unit System Consistency

Always maintain consistency within calculations. Convert all values to the same unit system (SI or Imperial) before performing engineering calculations.

Significant Figures

Engineering calculations require appropriate precision. Consider measurement accuracy and round results to meaningful significant figures.

Safety Factors

When converting stress or load values, remember to apply appropriate safety factors according to engineering standards and codes.

Standard References

Always verify critical conversions against engineering handbooks and standards (ASME, ISO, ASTM) for your specific application.
