Convert AWG gauge to mm and diameter. Use for sizing wire; for drop use voltage-drop-calculator. Input: AWG number. Returns specs. 100% client-side, files never leave browser.
Solve voltage, current, resistance, and power from any two knowns (V=IR, P=VI).
Calculate voltage drop over wire runs. Use for wiring; for sizing use wire-gauge-calculator. Input: length/load/AWG. Returns drop percent. 100% client-side, files never leave browser.
Total resistance for any list of resistors in series or parallel.
