Log <-> Linear Voltage

• [x] dBμV to Volts V = 10((dBμV - 120) / 20)
• [x] Volts to dBμV dBμV = 20log(V)+120
• [x] dBV to Volts V = 10(dBV / 20)
• [x] Volts to dBV dBV = 20log(V)
• [x] dBV to dBμV dBμV = dBV + 120
• [x] dBμV to dBV dBV = dBμV - 120

Log <-> Linear Power

• [x] dBm to Watts W = 10((dBm - 30)/10)
• [x] Watts to dBm dBm = 10log(W) + 30

Log <-> Linear Current

• [x] dBμA to μA μA = 10(dBμA)/20)
• [x] μA to dBμA = dBμA = 20log(μA)

dB Delta

• [x] Volts dB = 20log(V1 / V2)

• [x] Amps dB = 20log(A1 / A2)

• [x] Power dB = 10log(W1 / W2)

• [x] New voltage with dB delta Vnew = 10((dBdelta + 20log(given)/20)

• [x] New wattage with dB delta Wnew = 10((dBdelta + 10log(given)/10)

Term Conversion

• [x] dBm to dBμV dBμV = 90 10log(Z) + dBm
• [x] dBμV to dBm dBm = dBμV - 90 - 10log(Z)
• [x] dBμA to dBm dBm = dBμA + 10log(Z) - 90
• [x] dBm to dBμA dBμA = dBm - 10log(Z) + 90
• [x] dBμA to dBμV dBμV = dBμA + 20log(Z)
• [x] dBμV to dBμA dBμA = dBμV - 20log(Z)

Field Strength

• [x] dBμV/m to V/m V/m = 10(((dBμV/m)-120)/20)
• [x] V/m to dBμV/m dBμV/m = 20log(V/m) + 120
• [x] dBμV/m to dBμV/m2 dBμV/m2 = dBμV/m - 115.8
• [x] dBμV/m2 to dBμV/m dBμV/m = dBμV/m2 +115.8
• [x] dBμV/m to dBμA/m dBμA/m = dBμV/m - 51.5
• [x] dBμA/m to dBμV/m dBμV/m = dBμA/m + 51.5
• [x] dBμA/m to dBpT dBpT = dBμA/m + 2
• [x] dBpT to dBμA/m dBμA/m = dBpT -2
• [x] W/m2 to V/m V/m = Square[(W/m2)*377]
• [x] V/m to W/m2 W/m2 = (V/m)2/377
• [x] μT to A/m A/m = μT/1.25
• [x] A/m to μT μT = 1.25 * (A/m)
• [x] Wound coil flux density μT = (4Pi(Turns)(Amps)) / 20 ( radius, m)
