"dB" expresses a ratio between two different power levels.
15W can't be expressed in dB. It can only be expressed as some number of dB
more or less than some other power.
If the reference level is 1 watt, then 15W is written as " +17 dBW ".
That means " 17 dB more power than 1 watt ".
In most of electronics and telecommunications, the reference level is usually 1 milliwatt.
Using that common reference level, 15W is written as " +47 dBm ".
That means " 47 dB more power than 1 milliwatt ".
=========================================================
The question starts from 15 watts.
Using 1 watt as the reference level ...
(15 watts) divided by (1 watt) = 15.
10 log(15) = +11.76 dBW (11.76 dB more power than 1 watt)
Using 1 milliwatt as the reference level ...
(15 watts) divided by (0.001 watt) = 15,000
10log(15,000) = +41.76 dBm (41.76 dB more power than 1 milliwatt)

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 do you convert hz to db?
using bode-m plots , one can tranfer dB magnitude to gain and gain to frequency
How do you convert from db HL to db SPL?
dB SPL is a comparison of a sound level to what was thought to be the threshold of hearing, although today it is known that the value was too high. dB HL is a measure of hearing loss - a comparison of a subjects hearing compared to a 'normal' standard. As they are measure different things a direct comparison is not possible. The differences between dB HL and dB SPL, arise from isophonic curves. There is no direct (linear) formula to convert this but a set of formulas. For different frequencies, different values should be added. For eg., at 1kHz you can state that 0dB HL is around 2dB SPL while at 250Hz, 0dB HL is 12 dB SPL. db HL = db Hearing Level db SPL = db Sound Pressure Level
Convert 100W into decibels?
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).
What is 8.5 sones in db?
You can convert the loudness in sones to the loudness level in phons. 8.5 sones equals 70.9 phons. The convertion from sone to dB is only a guess. Scroll down to related links and read "Correlation between sones und phons".

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 do you convert dB to liters?
If I understand the question, it isn't possible to convert dB (a unit of sound energy) to litres (a unit of volume).
Moisture content in dry basis convert to wet basis?
wb = db/(db+100)
How do you convert dB to dBA?
It is impossible to convert dB to dBA. There is only a guess. Scroll down to related links and read "Correlation between sones und phons".
How do you convert hz to db?
using bode-m plots , one can tranfer dB magnitude to gain and gain to frequency
How do you convert dB to dBrnC?
0 dBrnc=-90dBm (1000Hz Toned)
How do you convert dBm to dB?
the first convert the power in dBm to MW, the define of dBm=10 log (P MW) -10 log ( 1mw). example: let P=-2 dBm convert this to dB? answer: Pmw= inv log(-2/10)=0.630mw*1000 micw/mw=630 microw 10log(630)=28dB
What is the formula to convert voltage levels to decibels?
Here you find the formula to convert voltage levels to decibels. Scroll down to related links and look at "How to calculate dB?"
How do you convert from db HL to db SPL?

How do you convert amps to dB?
You don't. They measure quite different things, so there is no standard conversion. Ampere is a unit of electrical current. Decibel (dB) is a measure of signal gain.
What is Difference between 15w-30 and 15w-40 oil?
15w means they are the viscosity (flow) when the oil is cold, the -30 and -40 is the viscosity of the oil when hot. Therefore the 15w-30 being the lower Viscosity means it will flow fast then the 15w-40 when the oil is hot.
