Decibels to A-weighted decibels
1 decibel in A-weighted decibels
1 dB = 1 dB(A)
dB(A) = dB × 1
To convert decibels to A-weighted decibels, multiply by 1. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works
The relationship is dB(A) = dB × 1. Both units measure sound, so the conversion is a fixed factor that never changes.
A-weighted decibel: Weighted to match human hearing sensitivity; the standard measure for noise exposure.
Common questions
- How many A-weighted decibels are in one decibel?
- One decibel equals 1 A-weighted decibels. dB(A) = dB × 1.
- How do you convert decibels to A-weighted decibels?
- Use dB(A) = dB × 1. So 10 dB is 10 dB(A).
- How many decibels are in one A-weighted decibel?
- One A-weighted decibel equals 1 decibels, which is the reverse of the conversion above.
- Is there more than one kind of A-weighted decibel?
- Weighted to match human hearing sensitivity; the standard measure for noise exposure.
