EMC Calculators
Focused tools for common EMC unit conversions and quick compliance margin checks. Pick the calculator that matches your measurement — each tool does one job clearly.
Conducted emissions
dBm ↔ dBµV
ConverterConvert between dBm and dBµV at any system impedance (50 Ω, 75 Ω, or custom).

Conducted units
ConverterConvert conducted emission units between dBµV, dBµA, dBm, and dBmA at a LISN impedance.
Open calculator →
RF power
ConverterConvert RF power between dBm, watts, dBW, and conducted voltage (dBµV) at a given impedance.
Open calculator →
RF voltage
ConverterConvert RF voltage between dBµV and linear units (µV, mV, V), plus peak, RMS, and peak-to-peak for sine waves.

Radiated field
V/m ↔ dBµV/m
ConverterConvert electric field strength between linear (V/m) and log (dBµV/m) units.
Open calculator →
E-field units
ConverterConvert radiated electric field strength between logarithmic (dBµV/m) and linear units (V/m, mV/m, µV/m).

E ↔ H field
ConverterConvert between electric field (E) and magnetic field (H) strength under plane-wave far-field conditions.
Open calculator →
Power density
ConverterConvert electric field strength to power density (W/m² or mW/cm²) for far-field radiated emissions.
Open calculator →
H-field units
ConverterConvert magnetic field strength between dBµA/m, A/m, Tesla, Gauss, and pT.
Open calculator →
Distance extrapolation
ConverterExtrapolate radiated field strength between measurement distances using the 20 dB/decade free-space rule.
