Hi(adsbygoogle = window.adsbygoogle || []).push({});

I´m a little bit confused regarding conversion to dB:

Regulations for a project I´m on say the maximum magnetic field strength allowed is 60 dBuA/m at 10 m. (here I chose 60 myself for simplicity...)

So the question is will this correspond to 1 A /m at 10 m (10log[1000000/1]=60 dB)

or will it correspond with 1 mA / m at 10 m since 20log[1000/1]=60dB.

should I use 20log or 10 log???

regards

t.
