The conversion from dB microvolts (dBuV) to dBm involves understanding that dBm represents power levels referenced to 1 milliwatt into a 50 Ohm load. dBuV measures voltage levels referenced to one microvolt. To convert dBuV to dBm, one must consider the load resistance, as the conversion is only meaningful in the context of power. A calculator is available online to assist with this conversion. Understanding these definitions is crucial for accurate conversions between voltage and power measurements.

dBm is dB above 1mW into a 50 Ohm load. by ""dbMicro" I believe you mean dBuV, or dB above a microvolt.

This website calculator also explains a little bit about how to convert between the two. Just remember that the dBm number assumes a 50 Ohm load resistance. Otherwise it would make no sense to talk about a conversion between a voltage and a power.

Thread 'I thought it was only Amazon that sold unsafe junk'

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
