How to Convert Pascals to Decibels
To convert pascals to decibels, divide the value by 50000.
The Formula
Decibels = Pascals ÷ 50000
Key Fact
1 decibel = 50000 pascals
Tip: To convert decibels back to pascals, multiply by 50000.
Pascals to Decibels
Convert pascals (Pa) to decibels (dB) with formulas, examples, and conversion tables.
Pa
dB
1 Pa = 2e-5 dB
Full precision:0.00002 dB
Step-by-Step Solution
To convert 1 pascals to decibels, we divide by 50000 because one decibel equals exactly 50000 pascals.
1 decibel = 50000 pascals
Since there are 50000 pascals in every decibel, we divide our value by this factor:
1 ÷ 50000 = 2e-5 decibels
So 1 pascals = 2e-5 decibels.
Quick check: 2e-5 × 50000 = 1 pascals
Example Conversions
Example 1: 1 Pa = 2e-5 dB
1 ÷ 50000 = 2e-5
1 ÷ 50000 = 2e-5
Example 2: 5 Pa = 0.0001 dB
5 ÷ 50000 = 0.0001
5 ÷ 50000 = 0.0001
Example 3: 10 Pa = 0.0002 dB
10 ÷ 50000 = 0.0002
10 ÷ 50000 = 0.0002
