6 mW equals approximately 7.78 dBm
Converting 6 milliwatts (mW) to decibel-milliwatts (dBm) results in about 7.78 dBm.
This conversion uses the formula that relates power in milliwatts to dBm, which is a logarithmic measurement. It shows the power level compared to 1 milliwatt, expressing the ratio in decibels, providing a convenient way to compare signal strengths.
Conversion Result
6 mW is roughly 7.78 dBm, meaning the power level is about 7.78 decibels above 1 milliwatt. This indicates a moderate signal strength, useful in radio, Wi-Fi, and other communications where power levels are expressed in dBm for clarity and comparison.

Conversion Formula
The formula to convert milliwatts (mw) to decibel-milliwatts (dBm) is dBm = 10 * log10(mW). This works because decibel measurements are logarithmic, expressing ratios of power levels. Logarithmic scales help compare large differences easily, especially in signal strength.
For example, to convert 6 mW: dBm = 10 * log10(6) ≈ 10 * 0.7781 ≈ 7.78 dBm. The log10 function calculates how many times 10 must be multiplied by itself to reach the given power level, then multiply by 10 for dBm.
Conversion Example
- Convert 2 mW:
- Apply formula: 10 * log10(2) ≈ 10 * 0.3010 ≈ 3.01 dBm.
- Convert 10 mW:
- Calculate: 10 * log10(10) = 10 * 1 = 10 dBm.
- Convert 0.5 mW:
- Compute: 10 * log10(0.5) ≈ 10 * (-0.3010) ≈ -3.01 dBm.
- Convert 20 mW:
- Calculate: 10 * log10(20) ≈ 10 * 1.3010 ≈ 13.01 dBm.
- Convert 0.1 mW:
- Compute: 10 * log10(0.1) ≈ 10 * (-1) = -10 dBm.

Conversion Definitions
mW
Millwatt (mW) measures power in thousandths of a watt, used to express small power levels in electronics and communication systems. It directly indicates the energy transmitted over a specific time, providing a simple unit for low-power signals.
dBm
Decibel-milliwatts (dBm) is a logarithmic unit describing power relative to 1 milliwatt. It expresses signal strength in decibels compared to 1 mW, making it easier to compare large or small power levels in radio, Wi-Fi, and audio devices.
Conversion FAQs
Why is dBm used instead of milliwatts in signal measurements?
Because dBm is logarithmic, it simplifies handling very large or small power differences, making it easier to compare and visualize signal levels across a broad range, especially in wireless communications where power varies widely.
Can I convert dBm back to milliwatts manually?
Yes, by using the inverse formula: mW = 10^(dBm/10). This allows precise conversion from a dBm value to its equivalent in milliwatts, helping to understand actual power levels in physical units.
What does a negative dBm value indicate?
A negative dBm indicates power levels below 1 milliwatt, meaning the signal is weak. For example, -3 dBm corresponds to approximately 0.5 mW, common in low-power wireless transmissions or sensitive receiver inputs.
