About Equation Engine

Equation Engine makes everyday engineering calculations reusable, without rebuilding a spreadsheet each time.

Enter an equation once and solve for whichever variable you need. Use an existing calculator or try your own equation, enter expressions and SI prefixes directly, and save or share a calculation to revisit later.

Equations are stored as LaTeX, and SymPy handles the algebra to solve for the selected unknown. Results come from deterministic mathematics.
