How do you convert a power ratio to decibels?

(PowerÂ Ratio)

Here, the power ratio represents the ratio of two power values, and the result in decibels will indicate the relative difference in power between them. Decibels are commonly used in various fields to express power levels, gains, losses, and other quantities in a more manageable and meaningful way.

Let's go through an example:

Suppose you have a power ratio of 100. To convert it to decibels:

DecibelsÂ (dB)

=

10

Ă

log

âĄ

10

(

100

)

DecibelsÂ (dB)=10Ălog

(100)

DecibelsÂ (dB)

=

10

Ă

2

DecibelsÂ (dB)=10Ă2

DecibelsÂ (dB)

=

20

DecibelsÂ (dB)=20

So, a power ratio of 100 is equivalent to 20 decibels (dB).
