Underwater acoustic unit conversion

Hi all

I have acoustic noise level value in dB vs 1 dyne/sq cm e.g. -10 db vs 1 dyne / sq cm. I need to convert it into dB ref 1upa unit. How i will convert it?

Thanks & Regards

and here's the definition of a pascal in SI

1 upa = $10^{-6}$ pascal

and here's the Newton

NOTE: 1 Dyne = $10^{-5}$ Newton
