Decibel milliwatts to Watts Calculator Calculator Usage Guide

Learn how to use the Decibel milliwatts to Watts Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the value of Decibel milliwatts (dBm) in the input field.
  2. Click the "Calculate" button to convert dBm to Watts.
  3. The result in Watts will be displayed in the output field.
  4. Use the "Reset" button to clear all input fields and results.

Understanding the Formula

The calculator uses the following formula to convert dBm to Watts:

P(W) = 10^(P(dBm)/10) / 1000

This formula works because:

  • 10^(P(dBm)/10) converts dBm to milliwatts
  • Dividing by 1000 converts milliwatts to Watts

Examples

Example 1: If you enter 0 dBm, the result will be 0.001 Watts (1 milliwatt).

Example 2: If you enter -30 dBm, the result will be 0.000001 Watts (1 microwatt).

Example 3: If you enter +20 dBm, the result will be 100 Watts.
