Conversion / Calculation Guide
Formula to Convert mW to dBm
Use this standard formula:
Step-by-Step Example
Example: Convert 100 mW to dBm
Step 1: Write the formula
dBm = 10 × log10(mW)
Step 2: Substitute the value
dBm = 10 × log10(100)
Step 3: Calculate log10(100)
log10(100) = 2
Step 4: Multiply
dBm = 10 × 2 = 20 dBm
Final Answer: 100 mW = 20 dBm
Another Quick Example
Convert 1 mW:
dBm = 10 × log10(1) = 0 dBm
Key Insight: Every 10x increase in mW adds +10 dBm.
