The conversion of 26 dBm to watts results in approximately 0.3981 watts.
To convert from dBm to watts, you use the formula: watts = 10^((dBm – 30) / 10). This calculates the power in watts by adjusting the dBm value to a logarithmic scale, then reversing it to a linear scale. For 26 dBm, it involves subtracting 30, dividing by 10, and calculating 10 raised to that power.

Conversion Formula
The formula to convert dBm to watts is watts = 10^((dBm – 30) / 10). It works because dBm measures power level in decibels relative to 1 milliwatt, so subtracting 30 converts it to decibels relative to 1 watt. Raising 10 to this power gives the linear power in watts. For example, with 26 dBm: (26 – 30) / 10 = -0.4, so watts = 10^(-0.4) ≈ 0.3981 watts.
Conversion Example
- Convert 20 dBm to watts:
- Subtract 30: 20 – 30 = -10
- Divide by 10: -10 / 10 = -1
- Calculate 10^(-1): 0.1 watts
- Convert 10 dBm to watts:
- Subtract 30: 10 – 30 = -20
- Divide by 10: -20 / 10 = -2
- Calculate 10^(-2): 0.01 watts
- Convert 40 dBm to watts:
- Subtract 30: 40 – 30 = 10
- Divide by 10: 10 / 10 = 1
- Calculate 10^1: 10 watts
- Convert 0 dBm to watts:
- Subtract 30: 0 – 30 = -30
- Divide by 10: -30 / 10 = -3
- Calculate 10^(-3): 0.001 watts

Conversion Definitions
dbm
dbm is a unit measuring power in decibels relative to 1 milliwatt, or 0.001 watt, used often in radio, telecommunications, and audio levels to express signal strength in a logarithmic scale.
watts
Watts are a standard unit of power measurement in the International System, quantifying the rate of energy transfer or consumption in electrical and mechanical systems in a linear way.
Conversion FAQs
Why is converting from dBm to watts important?
Converting dBm to watts helps in practical applications such as designing wireless systems, calculating power outputs, and ensuring compliance with power regulations, by translating logarithmic units into understandable watt values.
Can I convert any dBm value to watts using the same formula?
Yes, the same formula applies universally, but the watt result varies depending on the dBm input. The calculation remains consistent, with higher dBm values resulting in higher watt outputs.
What happens if I input a negative dBm value in the tool?
Negative dBm values indicate power levels below 1 milliwatt, resulting in watt calculations less than 0.001, which the tool handles accurately, showing very small watt values accordingly.
Is it possible to convert watts back to dBm?
Yes, by using the inverse formula: dBm = 10 * log10(watts) + 30. This allows converting watts into the decibel-milliwatt scale for comparison or analysis purposes.
