Guest jack Posted December 22, 2003 Share Posted December 22, 2003 the formula is: dBpower = 10 x log (power1(30)/power2(6)) 30/6 = 5 now on your calculator press log then 5... log 5 = 0,698 0,698 x 10 = 6,9 6,9 = 7 hope you understand Quote Link to comment Share on other sites More sharing options...
