Given P = 100 watts.
Reference sound intensity Po = 10^−12 W.
Reference sound intensity level LPo = 0 dB.
Get power level LP in dB when entering sound power P in watts.
Power level LP = 10×log (P / Po) dB = 10×log (100 / 10^−12)
= 140 decibels (dB).

How do you convert dB to DBi?
You cannot convert DBi to DB because they are not related. DBi is only for decibels in an isotropic radiator, while DB is only for decibels in a dipole antenna.
How much energy will a 100w light bulb convert to light and heat if it is left burning for 1hour?
Power = Energy/time 100W=Energy/360 Seconds Energy = 100/360 Energy ≈ 0.27 Joules
What is the abbreviation used for decibels?
The abbrevation used for decibels is dB.
Loudness or sound level is measure in units called?
decibels

What can be used to convert decibels?
You can use a pocket calculator.

I have 15 subwoofers at 180 decibels each how loud would that be in db in case your wondering yes there is a woofer that reaches 180db its called dd 9918Z 18?
15 subwoofers would produce 15 times as much power. log1015 = 1.176; to convert that to decibels, you have to multiply it by 10, so you get an increase of 11.76 decibels, in other words, 180 + 11.76 = 191.76 decibels. Since the 180 decibels probably includes some rounding, it makes sense to round the final result, too - for example, to 192 decibels.
How much is 3000 kHz in decibels?
' kHz ' and ' decibels ' are units for measuring completely different quantities. Neither one can be converted to the other one, any more than you can convert ' 30 miles per hour ' into dollars and cents.
Why is the abbreviation for decibels dB?
DeciBels
Does voltage current or power affect volume in a speaker?
Power (Watts)/ Decibels (if the speaker is efficient) 2 Watts = 93 decibels 4 Watts = 96 decibels 8 Watts = 99 decibels 16 Watts = 102 decibels 32 Watts = 105 decibels 64 Watts = 108 decibels 128 Watts = 111 decibels 256 Watts = 114 decibels 512 Watts= 117 decibels 1024 Watts = 120 decibels Some Volumes to Compare 10 decibels = normal human breathing 60 decibels = normal human conversation 110 decibels = power saw, car horn, shouting in ear, 120 decibels = jet aircraft close by, emergency vehicle siren, rock concert
