FAQ
About Chemistry Dashboard.
Do widgets and history sync across dashboards?
Favorites and widget pins are global. History entries are tagged by dashboard so each dashboard shows only its own activity — with a global export available on the hub.
Are widgets accurate for professional use?
Every widget uses the same Universal Converter Engine that powers our full converter tools — deterministic factor + offset math, IEEE-754 rounding, and validated non-negative constraints where required.
Can I use this offline?
Yes. Every dashboard is fully offline-first — no external APIs are called for calculations. Installing the app to your home screen keeps it available with no network.
Which formulas back the results?
Molar masses use IUPAC 2021 standard atomic weights, gas law uses R = 8.314462618 J/(mol·K), Coulomb constant k_e = 8.9875517873681764 × 10⁹, and Avogadro N_A = 6.02214076 × 10²³ — all CODATA 2018 values shown in each report.
Can I use hydrates and parentheses?
Yes. The formula parser accepts nested parentheses (Ca(OH)2, Fe2(SO4)3) and hydrate notation (CuSO4·5H2O or CuSO4.5H2O).
Are calculations offline?
Every calculator runs 100% client-side. The periodic table (Z 1–118) is embedded in the bundle — no API keys or network requests.
Can I export or print my results?
Yes — Markdown, CSV, JSON, and plain-text artifacts are generated for every run, with a print-friendly layout.
