The engineering toolbox

Get a clearer picture. Start with the numbers.

Practical material, layout and unit calculations to help prepare a better requirement. Estimates support a discussion; final manufacturing details need engineering review.

Scientific calculator, micrometer, steel ruler and machined block on an engineering desk
Useful numbers. Clear assumptions.

Workshop planning tools

Use consistent units and check your inputs. Material density, process and supplier specifications can change final results.

Sheet & plate weight

A rectangular plate, before holes, cut-outs or finishing. Dimensions in millimetres.

Enter your dimensions, then calculate.

Round bar weight

Solid circular bar. Dimensions in millimetres.

Enter your dimensions, then calculate.

Pipe & tube weight

Circular tube from outside diameter and wall thickness. Dimensions in millimetres.

Enter your dimensions, then calculate.

Bend allowance

Neutral-axis arc length. The K-factor is material- and tooling-dependent.

Enter your dimensions, then calculate.

Rectangular sheet layout

Compare two uniform orientations. Includes the gap between parts, but excludes edge margins and irregular shapes.

Enter your dimensions, then calculate.

3D print material planning

A rough mass allowance from model volume. Actual walls, supports and slicing change the result. No price is calculated.

Enter your dimensions, then calculate.

Unit converter

Length, mass, pressure and temperature conversions. Negative values apply only to temperature.

Enter your dimensions, then calculate.

Currency reference

Live reference rates from Frankfurter. Use your bank or supplier rate for commercial commitments.

Enter your dimensions, then calculate.
