Need to quickly convert between various RF signal measurement units? dB Calc performs lots of decibel related conversions:

Decibel / Neper / Ratio Conversions:
Enter in either the dB, Np (nepers), power or voltage ratio, and the other values will be calculated.

Decibel / Power / Voltage Calculations:
Enter in the one known value, and the others will be calculated. Select the correct units before entering in the value. You can change the units of the displayed (calculated values) by selecting the new units. Enter in the resistance before entering in the known value.

The following units are available:
dBmW - dB ref to 1 mW power
dBuV - dB ref to 1 uV
dBu - dB ref to 0.7746 V (audio)
dBV - dB ref to 1 V

uW - microwatts
mW - milliwatts
W - watts

uV - microvolts
mV - millivolts
V - volts

RMS Waveforms Conversions:
Conversion between rms, peak, peak-peak voltage and current values for a user entered resistance. Sine, square, and triangle waveforms are supported.

Pros and cons of dB Calc app for iPhone and iPad

dB Calc app good for

This app was exactly what I was looking for. Quick conversion between dB based units. Very useful. Creator very responsive to feedback and requests.
A handy app for E.E.s, but personally Id drop the Neper to make room for V1 V2 fields in addition to the ratio field.
I find this application to be very useful in my day-to-day work as an RF engineer its really quite nice.
Use the app every day and find it to be very useful and accurate.

Some bad moments

A nice app but needs a lot more. I would delete the top section and expand on the middle section to include additional RF and dB conversions. It will then become a nice and handy tool.

Usually dB Calc iOS app used & searched for

dbu, db power, dbu mobile, volt systems, decibel watt, and other. So, download free dB Calc .ipa to run this nice iOS application on iPhone and iPad.
