An enterprise-grade conversion dashboard: real-time fiat and crypto valuation (with a resilient offline fallback engine), data storage and bandwidth transfer times, Ohm’s law electrical solving, fluid dynamics, energy, speed and area — every computation 100% client-side with a local audit trail and RFC-4180 CSV export.
No. Live rates come from free public endpoints (open.er-api.com, CoinGecko) with no key. Four fallback stages — live, mirror, local cache, offline sandbox — guarantee the tool always works.
Data storage (KB→PB), bandwidth and file transfer times, Ohm’s law and kWh cost, fluid flow (L/s, m³/h, GPM, CFM), pressure (Pa, Bar, PSI, atm, Torr), energy (J, kWh, cal, BTU, Therms), speed and area.
Never. All math runs in your browser; the audit trail lives in your own localStorage and CSV reports are generated locally. No conversion data ever reaches a server.
Sandbox rates are deterministic engineering baselines used only when no live or cached rates are available. For exact financial figures, click “Sync Live Rates” while connected.
