First of all, we must know that dB and GdB are units of sound, dB is the abbreviation of Decibel, GdB is the abbreviation of Gigadecibel.
Then, we want to convert 138 dB into GdB, we should get the conversion formula of dB to GdB first.
Fortunately, through the Decibel to Gigadecibel converter page, we can easily get the dB to GdB conversion formula: 1 dB = 1.0e-9 GdB. The number 1.0e-9 is called the conversion factor of dB to GdB.
So, convert dB to GdB, just multiply dB by the conversion factor 1.0e-9.
1 dB = 1.0e-9 GdB
138 dB = 138 * 1.0e-9 GdB = 1.38E-7 GdB
The result is out: 138 dB = 1.38E-7 GdB.
Is not it simple?
If you still don’t understand, take it easy, we can give another example:
1 dB = 1.0e-9 GdB
954 dB = 954 * 1.0e-9 GdB = 9.54E-7 GdB
Thus, 954 dB = 9.54E-7 GdB.
