Power Conversion Formula:
From: | To: |
Definition: This calculator converts power measurements from decibel-milliwatts (dBm) to watts (W).
Purpose: It helps engineers, technicians, and network professionals convert between logarithmic and linear power units.
The calculator uses the formula:
Where:
Explanation: The formula converts from logarithmic scale (dBm) to linear scale (watts) by reversing the logarithmic calculation.
Details: Accurate power conversion is essential for RF engineering, network design, signal analysis, and equipment specifications.
Tips: Enter the power value in dBm (can be positive or negative). The calculator will display the equivalent power in watts.
Q1: What is dBm?
A: dBm is a logarithmic power measurement relative to 1 milliwatt (0 dBm = 1 mW).
Q2: Why convert dBm to watts?
A: While dBm is convenient for calculations, some equipment specifications and physics equations require linear power units.
Q3: What's the relationship between dBm and watts?
A: 0 dBm equals 1 milliwatt (0.001 W). Each 10 dB increase represents a 10x power increase.
Q4: Can I convert negative dBm values?
A: Yes, negative dBm values represent power levels below 1 milliwatt (e.g., -30 dBm = 0.000001 W).
Q5: How precise is this conversion?
A: The calculation is mathematically exact, but practical measurements may have equipment tolerances.
