1 pascal (Pa) is equivalent to 94 dBSPL.
Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of hearing)
Reference sound pressure level Lpo = 0 dB-SPL (Threshold of hearing level)
Get sound pressure level Lp in dB when entering sound pressure p = 1 Pa:
Lp = 20×log (p / po) dB = 20×log (1 / 2×10^−5) =
20×log (1 / 0.00002) = 20×log (50000) = 94 dB.

What is the difference between pascal and decibels?
Pascal means the pressure = force divided by area. Decibels means a logarithmic unit of measurement that expresses the magnitude of a physical quantity relative to a specified or implied reference level. Since it is a ratio of two quantities with the same unit, it is a dimensionless unit. The difference is like between a car and a banana.
