Load Inputs

Span

UDL (Uniformly Distributed Load)

kPa

LD (Linear Load)

kg/m

Deflection Limit

The workbook uses kg/m² for UDL. This calculator accepts kPa and converts it internally using 1 kPa = 101.9716 kg/m².

Formula Reference

UDL

UDL kPa is converted to kg/m², then the workbook’s uniformly distributed load deflection formula is applied.

LD

LD kg/m is applied using the workbook’s transverse linear-load deflection formula.
