⚡ Electrical Units Conversion

Convert between electrical potential, current, resistance, capacitance, and charge units. Supports Volts (V, kV), Amperes (A, mA), Ohms (Ω, kΩ, MΩ), Farads (F, µF), and Coulombs (C). Designed for electronics hobbyists, electrical engineers, and students.

Electricity conversion calculates equivalent measures across standardized metric, customary, and technical units using fixed mathematical ratios. Standardized in accordance with NIST Special Publication 811 and BIPM SI guidelines, enabling precision calculations between Ampere, Milliampere, Volt, Kilovolt, and 6 additional units.

Metrological Standards & Base Equation

Ohm's Law: V = I × R. 1 kV = 1,000 V. 1 A = 1,000 mA. 1 kΩ = 1,000 Ω.

All electricity conversion factors on this platform comply with NIST Special Publication 811 (Guide for the Use of the International System of Units) and the BIPM SI Brochure (9th Edition), utilizing exact rational ratios and IEEE-754 double-precision arithmetic to prevent rounding distortion.
