Conversion Formula

The formula to convert dBm to watts is Watts = 10^((dBm – 30) / 10). This works because dBm is a logarithmic measurement of power relative to 1 milliwatt. By subtracting 30, we shift from milliwatts to watts, then raise 10 to this power to get the watt value. For example, for 27 dBm:

• Subtract 30: 27 – 30 = -3
• Divide by 10: -3 / 10 = -0.3
• Calculate 10^(-0.3): approximately 0.5012 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
• Result: 20 dBm equals 0.1 watts.

• Convert 40 dBm to watts:
• Subtract 30: 40 – 30 = 10
• Divide by 10: 10 / 10 = 1
• Calculate 10^1: 10 watts
• Result: 40 dBm equals 10 watts.

• Convert 0 dBm to watts:
• Subtract 30: 0 – 30 = -30
• Divide by 10: -30 / 10 = -3
• Calculate 10^(-3): 0.001 watts
• Result: 0 dBm equals 0.001 watts.

• Convert 52 dBm to watts:
• Subtract 30: 52 – 30 = 22
• Divide by 10: 22 / 10 = 2.2
• Calculate 10^(2.2): approximately 158.49 watts
• Result: 52 dBm equals approximately 158.49 watts.
