Beam Deflection Unit Converter
Convert the most common beam-analysis units without opening a separate calculator. Use it for span, deflection, point load, distributed load, elastic modulus, and second moment of area.

Engineering Notes
- This page is focused on beam-serviceability inputs, so the unit list stays narrow and practical instead of trying to be a generic civil-engineering converter.
- Use the same basis on both sides of a calculation. A common source of error is mixing mm with cm^4 or ft with kN.
- For a full structural response after conversion, continue into the main beam solver or the formulas page.
