It is a conversion calculator that is used to convert the power in decibel milliwatts dBm to milliwatts mW. It uses a simple formula and programmed controls when performing the conversions. First, enter the value in decibel-milliwatts in the blank text field. The results in milliwatts will be displayed below the two controls at the bottom panel of the calculator. This calculator gives accurate results depending on the values entered in the blank text field. The first step is to enter the value in decibel-milliwatts 3 in the blank text field.
It will be shown as; 1. The same procedure can be repeated when you have new values in decibel-milliwatts. It is used to erase all data of previous calculations from the calculator. This means that the power conversion of decibel-milliwatts to watts is given by 10 raised to the power of decibel-milliwatts divided by The dBm to milliwatts conversion table can also be used to determine the conversion of common values from decibel-milliwatts to milliwatts based on a scale of dBm to 50 dBm.
Note that this calculator can only convert values from decibel-milliwatts to milliwatts. If the values are in milliwatts, we recommend using the mW to dBm converter. For example; Convert 3 decibel-milliwatts to milliwatts.
Solution The first step is to enter the value in decibel-milliwatts 3 in the blank text field.The decibel watt dBW is a unit for the measurement of the strength of a signal expressed in decibels relative to one watt. All calculated values will be shown. I wish to use an excel spread sheet to calculate the total Insertion Loss over an entire coaxial cable where there will be 8 to 10 power dividers installed with antenna isolators to 8 to 10 antennas.
I need to convert the formula below to a useable formula in the excel spread sheet so I can enter it into each cell where it is the output to the on of 8 to 10 antennas. Can you provide me with the formaula to insert into the excel spreadsheet? Hi Richard. Good luck, however. Your email address will not be published.

dBm - dBw Watts Conversion Chart
No, go wild with the decimals!Although voltage levels are unlikely to rise to significant levels which might cause damage for power levels measured in dBm, the voltages are often used in other calculations.
Three tables have been included.
These have been chosen because the voltages move from readings measured in millivolts to those in volts. Also as the milliwatts change to watts, the change in the table is made. This conversion table charts the values for dBm against milliwatts and the relevant voltage expressed in millivolts.
This conversion table charts the values for dBm against milliwatts and the relevant voltage expressed in volts. These tables of dBm, dBW, watts and miliwatts to volts are useful to discover the voltages present. It is applicable to many lower power applications.
dBm to mW Conversion
It is applicable to many medium power applications. It is applicable to many high power applications. Supplier Directory For everything from distribution to test equipment, components and more, our directory covers it. Selected Video What is an Op Amp? Featured articles.Phone: Email: Transmitted power must be configured correctly to prevent potential interference problems due to the effective isotropic radiated power exceeding the limits as defined in FCC part As defined in FCC part The antenna can only have a maximum gain of 6dBi.
If the power at the transmitter is lowered by 1dB, the antenna gain can be increased by an additional 3dB. For example, if an installation reduced power at the transmitter to 29dBm, it could use an antenna having a gain of 9dBi. In general, for every 1dB power reduction at the transmitter from 30dBm, an installation can add 3dB gain at the antenna. A breakdown of transmitter versus antenna gain is as follows: 30dBm transmit - 6dBi antenna 29dBm transmit - 9dBi antenna 28dBm transmit - 12dBi antenna 27dBm transmit - 15dBi antenna 26dBm transmit - 18dBi antenna 25dBm transmit - 21dBi antenna 24dBm transmit - 24dBi antenna.

P dBm ref 1 mW. V RMS. P watts.The power levels expressed in dBm or dBW may not always be as meaningful as power expressed in watts and therefore a simple conversion chart converting dBm to watts and dBW and vice versa can be very useful.
Many power levels themselves for power meters, spectrum analysers, signal generators are specified in dBm or dBW rather than watts. Also RF components such as mixers, oscillators and the like, as well as the interfaces between modules in RF equipment have their levels specified in dBm or dBW.
Radio transmitters may also have their output levels expressed in terms of dBW. As a result of this the quantities of dBm and dBW are used:. From this it can be seen that a level of 10 dBm is ten dB above one milliwatt, i. Similarly a power level of 20 dBW is times that of one watt, i. The chart below gives a tabulation of dBm to dBW and watts which can be useful in determining some quick rough estimates of the values of power in different formats.
With use the terms dBm, and dBW come to have their meaning and mentally it is possible to convert between them. However it is always useful to have a conversion table or chart to hand to be able to convert one to another.
As a result of this the quantities of dBm and dBW are used: dBm - This is a power expressed in decibels relative to one milliwatt. Supplier Directory For everything from distribution to test equipment, components and more, our directory covers it.
Featured articles.It is a conversion calculator that is used to convert the power in decibel-milliwatts dBm to Watts W.
It uses a simple formula and programmed controls to execute the conversions. Use the blank text field to enter the power in decibel-milliwatts. The results in watts will be displayed at the bottom panel of the calculator below the two controls. This calculator gives accurate results depending on the values you enter in the blank text field. The first step is to enter the value in decibel-milliwatts 0.
It will be shown as; 0. You can also repeat the same procedure using new values. It gives a new space so that you can perform more conversions.
This means that the power conversion of decibel-milliwatts to watts is given by 10 raised to the power of decibel-milliwatts divided by 10 and the result is then divided by one thousand. The dBm to watts conversion table can also be used to determine the conversion of common values from decibel-milliwatts to watts based on a scale of dBm to 50 dBm. For example; Convert 0. Solution The first step is to enter the value in decibel-milliwatts 0. Using the example above; Convert 0.
