25dB equal to how many watts?

That depends on you. If you want, you can say 1 watt should be 0 dB.


What is -2 db in watts?

To convert decibels (dB) to watts, you can use the formula: ( P = P_0 \times 10^{(dB/10)} ), where ( P_0 ) is the reference power level (usually 1 watt). For -2 dB, the calculation would be ( P = 1 \times 10^{-2/10} ), which equals approximately 0.63095 watts. Thus, -2 dB corresponds to about 0.631 watts.


How many watts does an EPIRB transmit?

An EPIRB typically transmits at a power of 5-6 watts in the 406 MHz frequency range for satellite distress communication.


How loud is 3 watts?

The loudness of sound is measured in decibels (dB), and the relationship between power (watts) and perceived loudness is not linear. Generally, a sound source producing 1 watt of power at a distance of 1 meter can reach about 120 dB, which is quite loud, comparable to a rock concert. Therefore, 3 watts could produce sound levels around 123-126 dB, depending on the efficiency of the speaker or sound source used. However, actual perceived loudness can vary based on the environment and other factors.


How loud is 130 watts?

The loudness of a sound is measured in decibels (dB), not directly in watts. However, in audio systems, 130 watts can produce a significant volume, often exceeding 100 dB, depending on the efficiency of the speakers used. This level is generally considered very loud and can potentially cause hearing damage with prolonged exposure. The perception of loudness also varies based on the environment and how sound is distributed in the space.

If transmitter power is increased from 200 Watts to 400 Watts how do you convert to Db form?

Decibels (db) is relative power, log base 2, times 3. Increasing power from 200 watts to 400 watts is doubling power, so the decibel change is +3 db.800 watts would be +6 db, 1600 watts would be +9 db, 100 watts would be -3 db, 50 watts would be -6 db, and so on.


How many watts is 98db?

It depends on the reference. If the reference electric power is P0 = 1 W (0 dB) then 98 dB equals 6309573444.8 Watts.

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).

How do you convert 13.936 dB to watts?

In power wattage increases by two times for every three DBs of increase. A starting point is needed to do this calculation. The equation you're looking for is 10*log |P| = P in dB for example, 0 dB = 1 watt 10 dB = 10 watts for 13.936dB, 10^1.3936 = 24.75 watts.


How do you convert 40w to db?

To convert power in watts to decibels (dB), you can use the formula: dB = 10 * log10(P2/P1), where P1 is the reference power (usually 1 watt) and P2 is the power you are converting (40 watts in this case). Plugging in the values, you would calculate: dB = 10 * log10(40/1) = 16.02 dB.


If a 13 dB gain antenna has 2 watts of power at the input what is the effective radiated power?

40 watts


How do you convert 15W to dB?

"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)


Calculate the power out put of an amplifier that has an input of 15 μw and a gain of 25dB?

If you want to work in watts, convert 25dB to a scalling factor: 3dB = 2 x input 10dB = 10 x input 20dB = 100 x input ...25dB = 10 ^ (25/10) = 316.2 x input So the output is 15 micro Watts x 316.2 = (4700)/(10^6) = 4.7 milli watts If you want to work in dB, then convert 15 micro watts to dB: 10 * log |P| = dB = 10*log |15 x 10^6| = -48.2dB ***When you have very small (ie negative) dB, it is often referred to in dBm, or 1/1000 of dB ( 30 dBm = 0 dB) so the output is -18.2dBm + 25 = 6.8dBm, or -23.2dB
