Understand the formula, not just the answer.
Enter a formula, choose what you want to solve for, and optionally add values with units. The lab explains variable roles, proportional relationships, rearrangement logic, dimensional consistency, sensitivity, assumptions, common mistakes, and a worked calculation without using unsafe expression evaluation.

symbol = number unit. Formula input accepts common plain-text, Unicode and simple LaTeX notation such as F=ma, F=m\\cdot a, A=\\pi r^2 and simple \\frac{a}{b} forms. Supported units include kg/g/mg, m/cm/mm/km, m³/L/mL, s/ms/min/h, m/s, km/h, m/s², N/kN, J/kJ/MJ, V/mV/kV, A/mA, Ω/kΩ/MΩ, Pa/kPa/bar/atm, mol, K, °C and °F. Values are converted only through explicit unit rules—never guessed.🔒 The deterministic preview never calls
eval() or executes formula text. Production AI may explain semantics, but numerical calculation remains isolated and rule-based where possible.Formula Insight Report
