dB Calculator vs dB Calculations
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
dB Calculator
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 dBCalculator software comprises five independent calculation tools: dBm Calculator: This tools helps to add and subtract an arbitrary number of power levels expressed in units of dBm and watt. Voltage Calculator: This tools helps to add and subtract correlated and uncorrelated voltage levels. Unit Converter: 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. dB Converter: This tool converts linear power and voltage ratios to dB and vice versa. VSWR Converter: This tool converts reflection quantities such as Voltage Standing Wave Ratio VSWR, reflection coefficient, reflected power, return loss and mismatch loss. PLEASE NOTE: Calculations based on correlated vs uncorrelated levels yield very different results. If you see an unexpected result, please verify the uncorrelated/correlated setting of this app first! The dBCalculator software is based on the application note 1GP77: R&S dBCalculator by Rohde & Schwarz GmbH & Co. KG www.rohde-schwarz.com/appnote/1GP77

Keep in mind that calculations based on coherent versus incoherent levels can yield significantly divergent results. If you encounter unexpected outcomes, ensure you first check the correlated/uncorrelated settings of this application. dbm Calculator: This functionality facilitates the addition and subtraction of various power levels expressed in dBm and watt units. Be aware of the versatile nature of this tool when dealing with power levels. VoltageCalculator: Designed for the addition and subtraction of both correlated and uncorrelated voltage levels. This tool ensures precision in managing voltage variations, providing flexibility in your calculations. Unit Converter: A versatile tool that computes the equivalent values for a given entry in units such as dBm, dBW, mW, W, mV, V, dBV, dBµV, and dBu. It accommodates individual impedance values, offering comprehensive conversions across a range of units to suit your specific needs.
