EMC Theory & Formulas

In Electromagnetic Compatibility (EMC) testing, precise unit conversion is important, Our calculators fully support converting dBuV, dBuA, dBuA/m, dBuW, uA, uF, and uT.

Voltage (Conducted Emissions): dB”V = 20 * log₁₀(V) + 120

Magnetic Field (H-Field): dB”A/m = 20 * log₁₀(A/m) + 120

Magnetic Flux Density (B-Field): dBpT ≈ dB”A/m + 1.984 (Free Space)

Current: dB”A = 20 * log₁₀(A) + 120
