All Calculators

Every tool runs in your browser: nothing to install, no sign-up, and nothing you type or upload leaves your device. Each calculator shows its working step by step, can be printed or saved as a PDF, and has a link you can copy to share the exact result.

Sheet metal gauge charts

• Sheet metal gauge chart — gauge to mm and inches for steel, galvanized, stainless and aluminum, with weight per square foot and square metre.
• Stainless steel gauge chart — U.S. Standard Gauge thickness of stainless sheet, with exact fractions.
• Aluminum gauge chart — Brown & Sharpe gauge thickness of aluminum sheet.
• Galvanized steel gauge chart — galvanized sheet thickness by gauge, coating included.

Weight calculators

• Metal weight calculator — plate, bar, tube, angle, channel and beam in steel, stainless, aluminum, copper, brass and more.
• Steel plate weight calculator — weight of a steel plate or sheet from length, width and thickness.
• Pipe weight calculator — weight per foot or metre from pipe size and schedule, or any OD and wall.
• Steel beam weight calculator — I-beam and H-beam weight from the section dimensions.
• Round bar weight calculator — weight of solid round bar by diameter and length, with a size chart and rebar sizes.
• Tube weight calculator — round, square and rectangular tube weight from outside size and wall.
• Angle iron weight calculator — equal and unequal steel angle weight per foot or metre.
• Steel coil weight calculator — coil weight, strip length and wraps from the diameters and strip width, or outside diameter from weight.

Bending

• Bend allowance calculator — bend allowance, bend deduction and flat blank length, plus K-factor from a test bend.
• Bend radius calculator — air-bend inside radius from the V-die, minimum bend radius and outside radius.
• K-factor calculator — sheet metal K-factor from radius, thickness and method, or from a test bend.
• Cone flat pattern calculator — flat pattern of a cone or truncated cone, with SVG and DXF to download.

Laser cutting and engraving

• Laser cutting cost calculator — cutting time and cost per part from cut length, pierces and your machine rate.
• Laser cut box generator — finger-joint box templates as SVG or DXF, with kerf compensation.
• Gear generator — involute spur gears and gear pairs as SVG or DXF.
• Photo to laser engraving — turn a photo into a dithered image at the right size and DPI for your laser.
• Laser spot size calculator — focused spot diameter, Rayleigh length and depth of focus from wavelength, M² and lens.
• Kerf calculator — kerf-bend cut spacing, laser kerf offsets for parts and holes, and pieces per board with blade kerf.

Results are estimates for planning and quoting; verify critical designs against the applicable standard.
