Electric Field Strength Converter
Convert radiated electric field strength between logarithmic (dBµV/m) and linear units (V/m, mV/m, µV/m).
Use this when: You are reading spectrum analyzer results, comparing to CISPR limits, or translating datasheet values.
Key formula
V/m = 10^((dBµV/m − 120) / 20)Example: Enter 120 dBµV/m → 1 V/m

Electric field strength units
This converter is the broader sibling of the dBµV/m to V/m tool. It moves among dBµV/m, V/m, mV/m, and µV/m so a datasheet, a limit table, and a hand calculation can share one number.
Reach for it when you are reading spectrum-analyzer results that were already converted to field strength, comparing CISPR limits, or translating a linear immunity level into the same units as a radiated-emissions plot.
