Bm and watts are units of measurement used to express power levels in various contexts, particularly in electronics and telecommunications.
Watts (W)
Watt is the standard unit of power in the International System of Units (SI). It represents the rate at which energy is transferred or converted. In the context of electrical power, one watt is equal to the power produced when one ampere of current flows through an electrical potential difference of one volt. Watts are commonly used to measure the power output or consumption of various electrical devices and systems.
dBm (Decibels milliwatt)
dBm is a logarithmic unit used to express power levels relative to one milliwatt (mW). It is often used in the context of measuring the power of electronic signals, especially in telecommunications and radio frequency (RF) systems.
How to convert dBm to watts
To convert a power value from dBm to watts, you can use the following formula:
P(W) = 1W ⋅ 10(P(dBm) / 10) / 1000 = 10((P(dBm)- 30) / 10)
Where:
- dBm is the power level in decibels milliwatt.
- 30 is the reference value representing 1 mW in dBm.
For Example – Convert 80 dbm to watts
Ans. P(W) = 1W ⋅ 10(80dBm/ 10) / 1000 = 100000W

FAQs on dBm to watts conversion
How do you convert dBm to watts?
To convert dBm (decibels milliwatt) to watts, you can use the following formula: Watts (W) = 10^((dBm - 30) / 10)
How many watts is 1 dBm?
1 dBm is equal to approximately 0.1 milliwatts (mW) or 0.0001 watts (W).
What is 10w in dBm?
To convert 10 watts (W) to dBm, you can use the formula: dBm = 10 x log10(10) = 10 x 1 = 10 dBm
What is 10 dBm power in watts?
To convert 10 dBm to watts, you can use the formula mentioned in question 1: Watts (W) = 10^((10 - 30) / 10) = 10^(-2) = 0.01 watts (W)
How is dBm calculated?
dBm is calculated using the formula: dBm = 10 x log10(P / 1mW) Where P is the power level in milliwatts.
What is dBm in voltage?
To convert dBm to voltage, you need to know the impedance of the circuit (usually 50 ohms in telecommunications). The conversion formula is: Voltage (V) = √(P x R)
