dBm or decibel-milliwatt is an electrical power unit in decibels (dB), referenced to 1 milliwatt (mW).
So The power in decibel-milliwatts (P(dBm)) is equal to 10 times base 10 logarithm of the power in milliwatts (P(mW)).
P(dBm) = 10 ⋅ log10( P(mW) / 1mW)
So The power in milliwatts (P(mW)) is equal to 1mW times 10 raised by the power in decibel-milliwatts (P(dBm)) divided by [10].
P(mW) = 1mW ⋅ 10(P(dBm) / 10)
1 milliwatt is equal to 0 dBm:
1mW = 0dBm
2 watt is equal to 33dBm:
2W = 2000mW = 33dBm
Convert decibel-milliwatts to milliwatts, watts, decibel-watts.

How to convert power in milliwatts (mW) to dBm.
So The power in dBm is equal to the base 10 logarithm of the power in milliwatts (mW):
P(dBm) = 10 ⋅ log10( P(mW) / 1mW)
For example: 1 what is the power in dBm for power consumption of 1000mW?
Solution:
P(dBm) = 10 ⋅ log10( 1000mW / 1mW) = 30dBm
For example: 2 what is the power in dBm for power consumption of 10mW?
Solution:
P(dBm) = 10 ⋅ log10( 10mW / 1mW) = 10dBm
How to convert power in dBm to milliwatts (mW).
So The power in milliwatts (P(mW)) is equal to 10 raised by the power in dBm (P(dBm)) divided by 10?
P(mW) = 1mW ⋅ 10(P(dBm) / 10)
For example: 1 what is the power in milliwatts for power consumption of 10dBm?
Solution:
P(mW) = 1mW ⋅ 10(10dBm / 10) = 10mW
For example: 2 what is the power in milliwatts for power consumption of 30dBm?
Solution:
P(mW) = 1mW ⋅ 10(30dBm / 10) = 1000mW
How to convert power in watts (W) to dBm.
The power in dBm is equal to the base 10 logarithm of the power in watts (W) plus 30dB:
P(dBm) = 10 ⋅ log10( P(W) / 1W) + 30
For example: 1 what is the power in dBm for power consumption of 10W?
Solution:
P(dBm) = 10 ⋅ log10( 10W / 1W ) + 30 = 40dBm
For example: 2 what is the power in dBm for power consumption of 1000W?
Solution:
P(dBm) = 10 ⋅ log10( 1000W / 1W ) + 30 = 60dBm
How to convert power in dBm to watts (W).
The power in watts (P(W)) is equal to 10 raised by the power in dBm (P(dBm)) minus 30dB divided by 10:
P(W) = 1W ⋅ 10( (P(dBm)- 30) / 10)
For example: 1 what is the power in watts for power consumption of 50dBm?
Solution:
P(W) = 1W ⋅ 10( (50dBm - 30) / 10) = 100W
For example: 2 what is the power in watts for power consumption of 60dBm?
Solution:
P(W) = 1W ⋅ 10( (60dBm - 30) / 10) = 1000W
How to convert power in dBW to dBm.
So The power in dBm is equal to the base 10 logarithm of the power in watts (W).
P(dBm) = P(dBW) + 30
For example: what is the power in dBm for power consumption of 30dBW?
Solution:
P(dBm) = 30dBW + 30 = 60dBm
How to convert power in dBm to dBW.
So The power in dBW (P(dBW)) is equal to 10 raised by the power in dBm (P(dBm)) divided by 10.
P(dBW) = P(dBm) - 30
For example: what is the power in watts for power consumption of 50dBm?
Solution:
P(dBW) = 50dBm - 30 = 20dBW
dB is a relative unit that describes gain and dBm is an absolute unit referenced to 1 milliwatt (mW).
So you can't convert dB to dBm.
