This tool converts RF power between:

• Watts (W) — linear power
• dBm — power relative to 1 milliwatt
• dBW — power relative to 1 watt

Formulas:

• \( \text{dBm} = 10 \cdot \log_{10}(P_{\text{W}} \times 1000) \)
• \( \text{dBW} = \text{dBm} - 30 \)
• \( \text{Watts} = 10^{\left(\frac{\text{dBm}}{10}\right)} \div 1000 \)

dBm is commonly used in RF system design, link budgets, and antenna calculations. This calculator makes it easy to convert between engineering units at any power level.
