Calculeaf user guide · Updated 2026-08-16

A math region is where you write the calculation. This section is the language of that field: assignment, units, conversion, symbols, and the two controls that feed values in — sliders and dropdown lists.

A Calculeaf worksheet with unit-aware assignments for a uniformly distributed load and the reaction that uses them.
Assignments with units, then a formula that uses those names. That is the core of a Calculeaf sheet.

Pages in this section

  1. Expressions and assignment — := defines a name; a trailing = shows the result.
  2. Variables and scope — names exist for everything after them in reading order.
  3. Units — type them after the number, or pick them from the Math ribbon.
  4. Unit systems — SI, USCS, or CGS on the Home ribbon.
  5. Conversion with to() — lock a result to a unit, or click the result chip.
  6. Autocomplete — suggestions for variables and units as you type.
  7. Greek letters and symbols — ribbon, typed names, and Alt shortcuts.
  8. Sliders — drag a numeric assignment through a range.
  9. Dropdown lists — each entry injects the same variables with different values.
