Engineering Calculators

Quick online tools for common mechanical engineering calculations

Use these interactive calculators for quick engineering calculations. All computations are performed in your browser - no data is sent to our servers.

Beam Deflection Calculator

Calculate deflection for simply supported beams with central point load

Note: This calculator assumes a simply supported beam with central point load. Deflection = (P × L³) / (48 × E × I)

Material Weight Calculator

Calculate weight for common shapes and materials

Unit Converter

Convert between common engineering units

Common Conversions:
• 1 inch = 25.4 mm
• 1 pound-force = 4.448 N
• 1 psi = 6894.76 Pa
• 1 lb·ft = 1.35582 N·m

Pressure Vessel Thickness

Estimate minimum wall thickness for cylindrical pressure vessels

Note: Based on ASME Section VIII Division 1 formula for cylindrical shells.
t = (P × R) / (S × E - 0.6 × P) + C
