Electrical Field Calculator

Electrical Field Calculator is a focused field-reference app for quick electrical estimates. Use it to check voltage drop, calculate Ohm's law values, and convert watts to current with power factor. Built for electricians, apprentices, maintenance technicians, HVAC/service technicians, and capable field users, the app keeps the current release deliberately narrow: fast reference calculations, local saved estimates, clear assumptions, and user-controlled report sharing. Current tools: - Voltage drop estimate using voltage, current, one-way circuit length, and conductor resistance per 1,000 ft. - Ohm's law values for watts and resistance from voltage and current. - Power conversion for current from watts, voltage, and power factor. Field workflow: - Save estimates with a project or circuit label. - Restore recent saved estimates. - Share, email, and print clean estimate summaries through Android system actions. - Review field notes, assumptions, and the estimating-only disclaimer. - Use the app offline with no ads and no account requirement. Privacy-focused app posture: - Saved estimates and settings stay on your device. - No app-owned account, login, cloud sync, ads, analytics, billing, tracking SDK, or app-owned network transfer was found in current source evidence. - Fresh MR3 generated manifest checks found no app permissions and no INTERNET permission. Electrical Field Calculator is for field-reference estimates only. It does not provide NEC compliance, local code approval, engineering design, installation approval, wire sizing or ampacity approval, breaker or protection sizing, derating approval, conduit fill, box fill, load calculations, permit guidance, inspection approval, or safety certification.
