The dBCalculator software comprises five independent calculation tools.

PLEASE NOTE: Calculations based on coherent vs incoherent levels yield very different results. If you see an unexpected result please verify the uncorrelated/correlated setting of this app first

dbmCalculator:
This tools helps to add and subtract an arbitrary number of power levels expressed in units of dBm and watt.

VoltageCalculator:
This tools helps to add and subtract correlated and uncorrelated voltage levels.

UnitConverter:
This tool calculates for an entry using a unit such as dBm dBW mW W mV V dBV dBµV and dBu the corresponding values for all other units for individual impedance values.
