Convert 2.2 V pp to dBm?

How do you convert from dBm to dBi?
Well, the question your asking is basically impossible. It's like asking to convert a gallon of water into cans of pop. It is possible to convert the gallon of water into cans of water not soda. So you can convert dBm to watts, not dBi.
How do you convert dBm to watts?
dBm is defined as power ratio in decibel (dB) referenced to one milliwatt (mW). It is an abbreviation for dB with respect to 1 mW and the "m" in dBm stands for milliwatt. dBm is different from dB. dBm represents absolute power, whereas in audio engineering the decibel is usually a voltage ratio of two values and is used then to represent gain or attenuation of an audio amplifier, or an audio damping pad.
What is 75 dBm converted into dBW?
dBw=dBm-30 then 75-30=45 dBw dBw=dBm-30 then 75-30=45 dBw dBw=dBm-30 then 75-30=45 dBw
Difference between dB dBm and dBi?
dB or dBW relativ to 1W : dBm for dB relativ to 1 milliwatt. 0 dBm= 1 mW = -30dBW . Its interesting,but these terms are used interchangeably at times, erroneously.The term dBm is used by communications engineers and it is absolute.Most Power meters commercially available have this scale. It is : dBm=10log(base 10)(P1/P2) at two different Power points.Power is read always across a 50 Ohm resistor.IEEE has made this a standard and 1mW=0dBm(-40dBm is 100nW accross 50 Ohm and +20dBm is 100mW). As far as I know dB(not DB)refers simly to gain(and loss/attenuation as -dB).It is different this time as the equation is not Power but a simple ratio: dB=20log(base 10)(Gain or attenuation).One can have a reference and above that reference he is talking in positive dBs(Gain) and below in negative dBs(loss or attenuation).Such scales can then be modified as we have done for Acoustic Emission where we talk in dBae and our refence is the "perfect" sensor giving us ONLY 1microVolt(!) Peak output noise.Anyway a good goal.So for 40dBae a sensor/Amplifier(40dB Gain)output across a 50 Ohm resistor is 10mV.
Convert db to dbm?
Here's how to convert dB units (with usually a 1 Watt or whatever 1 value as reference) to dBm units (with a 1 miliWatt reference value):x= value to be convertedx [dB]= x + 30 [dBm]Proof:P= 1 Watt--> 10*log10(1)= 0 [dB] (this is 1 Watt in dB)--> 10*log10(1/(1*10^(-3)))= 10*log(1*10^3)= 30 dBm (this is 1 Watt to dBm)Now, if you do whatever number of examples you want to do, you'll end up in concluding the conversion dB to dBm is totally linear without of actually having to proof the linear properties. (i'm too lazy to write it here).Hope this helps....Regards,STMI

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
How do you convert 10W to dBm?
dBm us almost exactly the same as dB. The only difference is that there is a reference of 1 Watt = 0 dB, and 1 mW = 0 dBm. dBm is defined as power ratio in decibel (dB) referenced to one milliwatt (mW). It is an abbreviation for dB with respect to 1 mW and the "m" in dBm stands for milliwatt. dBm is different from dB. dBm represents absolute power, whereas in audio engineering the decibel is usually a voltage ratio of two values and is used then to represent gain or attenuation of an audio amplifier, or an audio damping pad. PdBm = 10*log10(1000*10W) = 40dBm
What is a dbm in relation to radio frequency?
'dBm' is a unit used to describe power. It's very very common in measurementsof signal levels in radio transmitting and receiving equipment, mainly because it'sa unit that can describe such an enormous range of low- to high- powers withoutawkward numbers. But there's no reason that any power level encountered in anyphysical system can't be expressed in units of dBm .Definition:'dBm' doesn't describe an amount of power that you can hold in your hand.It describes how any amount of power compares to 1 milliwatt (0.001 watt).Any power level, in dBm = 10 x log ( the power level/0.001 watt )1 milliwatt = Zero dBm2 milliwatts = +3 dBm1/2 milliwatt = -3 dBm10 milliwatts = +10 dBm100 milliwatts = +20 dBmExamples:-- 1 millionth of a millionth of a watt = 1 'picowatt' = 0.000 000 000 001 watt = -90 dBm-- 1 whole watt = 1.0 watt = +30 dBm-- 1 'kilowatt' = 1,000 watts = +60 dBm-- Maximum capacity of Braidwood Nuclear Generating Station,serving Chicago and northeastern Illinois . . . . .2,360 MegaWatts = 2,360,000,000 watts = +123.7 dBm

Milliwatts to dbm conversion?
The 'm' in dBm means the power is referenced to 1mW. So, the power in dBm equals 10 times the log of the power in mW, or P(dBm) = 10*log(P(mW)/1mW). For example, 1W = 1000mW, so 10*log(1000/1) = 30dBm.
How do you get power output with a given power input of 20dbm and three power gain which is Ap1 equals 10 ap2 equals 4 ap3 equals 23?
Two ways to do it. In this particular problem, it's a matter of opinionwhich one is easier and which one is harder.Way #1:Convert dBm to watts, multiply by gains, convert output watts to dBm.+20 dBm = 0.1 watt.Output power = (0.1 watt) x (ap1) x (ap2) x (ap3) = 0.1 x 10 x 4 x 23 = 92 watts = +49.64 dBmWay #2:Convert each gain ratio to dB, then add all dB to input power.ap1 = 10 = 10 dBap2 = 4 = 6.02 dBap3 = 23 = 13.62 dB+20 dBm + 10dB + 6.02 dB + 13.62 dB = +49.64 dBm

I am trying to convert a measurement from milliwatts to dBm which is done by the following formula dBm equals 10Log10milliwatts was wondering how to put this formula into Microsoft Excel Anyone know?
Put the power in milliwatts in cell A2, and then use the following formula to get the power in dBm. =10 * LOG(A2)
