The conversion of 10 dBm to d results in 0 d. This is because 10 dBm equals 0 d, as the d unit measures relative power levels without reference to a specific power level.
Since dBm measures power in relation to 1 milliwatt, converting it to d involves subtracting 30 from the dBm value. So, 10 dBm minus 30 gives 0 d, indicating no gain or loss relative to the reference point.
What is the result of 10 dBm to d?
The result of converting 10 dBm to d is 0 d. This means there is an equal power level without gain or attenuation relative to the reference.

Conversion Formula
The formula to convert dbm to db subtracts 30 from the dbm value because 0 dBm equals 1 milliwatt, and each 10 dB increase represents a tenfold power increase. Therefore, converting involves: db = dbm – 30. For example, 10 dBm minus 30 is 0 d, indicating no change in power level.
Conversion Example
- Convert 20 dBm to d:
- Start with 20 dBm
- Subtract 30 to convert to d
- 20 – 30 = -10 d
- Result: -10 d
- Convert 0 dBm to d:
- Start with 0 dBm
- Subtract 30
- 0 – 30 = -30 d
- Result: -30 d
- Convert 25 dBm to d:
- Start with 25 dBm
- Subtract 30
- 25 – 30 = -5 d
- Result: -5 d

Conversion Definitions
dbm is a measure of power relative to 1 milliwatt, used mainly in radio and telecommunications to indicate signal strength; 0 dBm equals 1 milliwatt, and each 10 dB increase multiplies power by ten. It provides a standardized way to compare power levels.
db is a logarithmic unit expressing the ratio between two power levels, often used for gain, attenuation, or signal strength. It indicates how much one power level differs from another, with positive values showing amplification and negative values indicating loss.
Conversion FAQs
Why is 10 dBm equal to 0 d?
Because converting from dbm to d involves subtracting 30, 10 – 30 gives 0, meaning 10 dBm is equal to 0 d, showing no gain or loss relative to the reference power level.
Can I convert dbm to d in my head?
Yes, by remembering that the conversion simply subtracts 30 from the dbm value. For example, for 10 dBm, 10 minus 30 equals 0 d; for 25 dBm, 25 minus 30 equals -5 d.
What does a negative d value indicate?
A negative d value indicates that the power level is below the reference level of 1 milliwatt, meaning the signal is weaker compared to the standard, for example, -10 d shows attenuation.
Is the conversion from dbm to d linear?
Yes, it is linear because each increase of 10 dBm corresponds to a tenfold increase in power, and the conversion formula maintains this relationship through simple subtraction.
