Conversion Formula
Ohm's Law (relates V, I, R — requires knowing two to find the third): V = I × R • I = V ÷ R • R = V ÷ I Power relationships: P = V × I • P = I² × R • P = V² ÷ R This converter handles within-quantity conversions (V↔mV↔kV, W↔kW↔MW, etc.). Cross-quantity conversions (e.g., watts to volts) require a third known value.
