dB isrelativenumber while dBm is anabsolutenumber. There’s no explicit conversion between the two. As an example 3 dBm cannot be converted to an equivalent dB value. You can however subtract two dBm numbers and the result is in dB. This dB value does not represent the sum or difference ...
dB是功率增益的单位, 一个纯计数单位:dB= 10logX。表示一个相对值。当计算A的功率相比于B大或小多少个dB时,可按公式10 lg A/B计算。例如:A功率比B功率大一倍,那么10 lg A/B = 10 lg 2 = 3dB。也就是说,A的功率比B的功率大3dB;如果A的功率为46dBm,B的功率为40dBm,则可以说,A比B大6dB;如果A...
How to convert dBm to mW The power conversion from dBm to mW or Watt is given by the formula: P(dBm)= 10(P(mW)/10) Example 1: Convert 20 dBm to milliwatts: P(mW)= 10(20/10)= 100 mW So, the power of 20 dBm is equal to 100 mW or 0.1 W (Watt). ...
How to convert mW to dBm To convert milliwatts (mW) to dBm, you can use the following formula: P(dBm) = 10 ⋅ log10( P(mW) / 1mW) For Example – Convert 33 dbm to mw Ans. P(dBm) = 10 ⋅ log10( 33mW / 1mW) = 330 dBm See Also hp to Watt conversion kW to hp conve...

mW to dBm Conversion dBm Definition: dBm is the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). The formula bellow can be translated as: "the power P(dBm) in dBm is equal to 10 times the base 10 logarithm of the power P(mW) in milliwatts (mW...
