Factor of Safety Calculator

Factor of Safety

Calculate the structural integrity of a design by comparing material strength to actual working stress.

Factor of Safety (FoS)
2.50
Safe

Design Standards

Aerospace

Typically 1.25 to 1.5. Weight is critical, so margins are tighter but precisely calculated.

Civil Engineering

Typically 2.0 to 3.0. Buildings and bridges prioritize safety over weight.

Pressure Vessels

Typically 3.5 to 4.0. High risk of catastrophic failure requires large safety margins.
