Visible formulas

Every result shows the equation behind it, not just a number.

Unit-aware

Enter values in the units you have - SI or US customary.

Calculation trace

See the formula, the substitution, and the result, in order.

Assumptions shown

Every calculator states what it assumes and where it stops applying.

A relatively small set of formulas does most of the work across engineering - the ones a curriculum keeps returning to because nearly…

Mechanical engineering runs on a smaller set of formulas than the size of the field suggests - these eight cover power transmission (belts,…

Civil and structural site work leans on a compact set of formulas more than the breadth of the field suggests - these twelve cover…
