Calculation Formula

Percentage = 10^(dB/10) - 1

Where:
- dB is the decibel value input
- The formula converts the logarithmic dB scale to a linear percentage scale

Learn how to use the Decibel to Percentage Calculator and understand its applications

How to Use This Calculator

  1. Enter the decibel (dB) value in the input field. Negative values are supported (e.g., -3 dB).
  2. Click the "Calculate" button to convert the dB value to percentage.
  3. The result will be displayed in the percentage field.
  4. Click "Reset" to clear all input fields and results.

Understanding the Formula

The formula used for this conversion is:

Percentage = 10^(dB/10) - 1

This formula converts the logarithmic decibel scale to a linear percentage scale. For example:

  • 0 dB = 1.0 or 100%
  • -3 dB = 0.5 or 50%
  • +3 dB = 1.995 or approximately 199.5%
  • -10 dB = 0.1 or 10%

Practical Applications

This calculator can be used in various scenarios:

  • Audio engineering for comparing signal levels
  • Electronics for voltage and power level conversions
  • Telecommunications for signal strength measurements
  • Acoustics for sound pressure level comparisons
