SciCalc Sidekick — Scientific Calculator

A precision scientific calculator beside every page: LaTeX-typeset results, unit-aware math, persistent history. By Science Digest.

**Stop breaking your flow to hunt for a calculator.** SciCalc Sidekick lives in Chrome's side panel — always one keystroke away, never a lost tab — so you can compute right beside the paper, worksheet, or spec you're reading. **What it does** - **Expression engine** — type whole expressions, not button sequences: `(3.2e-4 * sin(pi/6))^2 / sqrt(2)`, evaluated as typed. Trig, logs, roots, factorials, permutations/combinations, and more. - **Unit-aware math** — `5 kg * 9.81 m/s^2 → 49.05 N`, `2 atm → 202.65 kPa`. Dimension mismatches come back as readable messages, never NaN. - **LaTeX-quality output** — every result is beautifully typeset with KaTeX. Copy any result as LaTeX for your report. - **Persistent history** — every calculation is saved on your device like a lab notebook: re-run, copy, or export. Survives restarts; never leaves your machine. - **DEG/RAD & high precision** — an always-visible angle-mode indicator, plus a 50+ significant-digit mode for when float64 isn't enough. - **Nine formula presets** — escape velocity, gravitational force, kinetic energy, ideal gas law, pendulum period, projectile range, population growth, molarity, and orbital period. Fill in the knowns, get a typeset answer. - **Quick popup + right-click capture** — a one-line quick calc from the toolbar, and "Send to SciCalc" to pull a selected number (with its units) straight into the panel. **Your data stays yours.** All computation happens on your device. Your calculations are never transmitted anywhere. The only thing that ever leaves the extension is your license key, sent to the license server to verify Pro — nothing else.
