Built for beam analysis

Structural Engineering Unit Converters

Convert the units engineers actually use for beam loads, bending moments, stress, self-weight, and section properties—then carry compatible load values straight into the Beam Calculator.

Beam analysis converters

These converters map directly to loads, diagrams, stress results, and self-weight workflows in a beam model.

Open Beam Calculator
Bending Moment Unit Converter Convert bending moment units used in beam analysis, applied moments, bending moment diagrams, hand checks, and metric-to-imperial calculations. Distributed Load & Line Load Converter Convert the force-per-length units used for uniform and varying beam loads. You can also turn an area pressure into a beam line load using tributary width. Force & Point Load Converter Convert point loads, support reactions, and shear forces between kN, N, kip, and pound-force. Stress Unit Converter Convert bending stress, shear stress, modulus, and material strength values between MPa, ksi, psi, kPa, GPa, and psf. Material Density & Unit Weight Converter Convert mass density for steel, concrete, aluminum, and wood, then calculate unit weight for beam self-weight checks.

Supporting utilities

Section and quantity converters

Use these for section-property inputs, geometry, material quantities, and consistent model dimensions.

Open Section Properties
Moment of Inertia Unit Converter Convert second moment of area (area moment of inertia) between mm⁴, cm⁴, m⁴, in⁴, and ft⁴ for beam deflection and stress calculations. Engineering Length Converter Convert beam spans, support and load locations, deflections, and section dimensions between metric and imperial length units. Engineering Area Converter Convert cross-sectional area, tributary area, and bearing area between common metric and imperial units. Engineering Volume Converter Convert member, material, and concrete volumes for quantity, mass, and self-weight calculations. Engineering Mass Converter Convert member and material mass between metric tonnes, kilograms, grams, pounds, long tons, and short tons.

Pressure-to-beam workflow

Turn floor or roof pressure into a beam load.

Convert psf × tributary width to plf, or kPa × tributary width to kN/m. Then send the result into the distributed-load dialog with the magnitude already filled in.

Engineering context

Each page explains where the unit appears in beam analysis—not just the arithmetic.

Consistent quantities

Mass, force, density, unit weight, pressure, and line load remain clearly separated.

Mobile friendly

Large touch targets and responsive fields make on-site and desk-side checks practical.
