About

This app provides five distinct calculation tools for power levels, voltage, and signal reflection. It helps convert between various units like dBm, watt, and dB, and calculate VSWR and reflection coefficients.

✓dBm and watt power level calculations
✓Correlated and uncorrelated voltage calculations
✓Unit conversion for dBm, dBW, mW, W, mV, V, dBV, dBµV, dBu
✓Linear power/voltage ratios to dB conversion
✓VSWR, reflection coefficient, and mismatch loss calculations

The app you’ve been looking for

I was looking for a unit converter, and stumbled on to this awesome app. Are you wondering what your equivalent wattage would be with your 1000 W +7.5 dB? Type it in exactly that way, and done!

It’s truly an awesome app that will save you loads of time.

Incorrect Calculations!

Overall the interface is not very user friendly for such a simple app and the unit Convertor does not calculate properly from dBm to Watts.

Wrong calc

The dB micro volt calculations are incorrect on this app. Everything else seems fine but it doesn't matter which you select, it alway converts to dBV. This should be an easy fix R&S.
