<h2>Prevodník miliwattov (mW) na decibel-miliwatty (dBm).</h2>
<p>Pri práci s bezdrôtovými systémami dodávatelia často poskytujú merania výkonu v rôznych jednotkách. Niektoré používajú miliwatty (mW), zatiaľ čo iné používajú decibel-miliwatty (dBm). Tento obojsmerný prevodník uľahčuje prácu v oboch meracích jednotkách.</p>
