Steel Calculators
A complete set of free steel and metal engineering calculators — weight and dimensions, structural beam design, and material property conversions. Every tool runs instantly in your browser, shows the formula behind the result, and includes the reference data it uses.
Weight & dimensions
Metal Weight Calculator
All shapes and alloys in one tool — round, square, flat and hex bar, tube, pipe, plate and angle. Start here.
Sheet Metal Gauge Chart
Gauge to mm and inches for steel, galvanized, stainless and aluminum, plus reverse lookup.
Steel Plate Weight
Plate and sheet weight from thickness and area.
Steel Bar Weight
Round, square and flat bar weight.
Steel Tube Weight
Round, square and rectangular tube and pipe.
Steel Angle Weight
Equal and unequal angle sections.
Rebar Weight
Reinforcing bar by metric size or US bar number.
Structural design
I-Beam Load Capacity
Safe uniformly distributed load from section, span and grade.
I-Beam Span
Maximum span for a given load, checked for bending and deflection.
Beam Deflection
Four load cases — UDL, point load, simply supported or cantilever — checked against L/360, L/240 and L/180.
Steel Beam Calculator
Size and check beams for load, span and deflection.
I-Beam Cost
Material cost from length, weight per foot and price.
Material properties & fabrication
Hardness Conversion
HRC, HRB, Brinell, Vickers and approximate tensile strength.
Carbon Equivalent (Weldability)
CEV, Pcm and CET from composition, with weldability and preheat guidance.
Thermal Expansion
Length change from temperature, with coefficients for common steels.
Temperature Expansion
Expansion by temperature range.
Steel Terms Dictionary
Definitions for the terminology used across these tools.
Conversion
Engineering Unit Converter
MPa, ksi, psi, kgf/mm²; °C/°F/K; mm, inch, mil; kg, lb and tons.
Sheet Metal Gauge Chart
Gauge to mm and inches, and back, for four materials.
How to pick the right tool
For buying or shipping material, start with the Metal Weight Calculator — it covers every common shape and alloy in one place. For sheet work, convert gauge first with the gauge chart, then calculate weight. For structural members, size the section with the load capacity and span calculators, and check both bending and deflection. For specifying or comparing material, use the hardness converter alongside our steel grade datasheets.
All results are nominal values for estimation and preliminary design. Confirm against the governing standard and mill certificate before construction or procurement.
