Decibel (dB) Calculator Decibel Calculator Decibel Calculator Convert Power Gain (P1/P2) to Decibels Power Gain (P1/P2) Convert Example: For a power gain ratio of 100 (P1/P2 = 100), the decibels are calculated as: This calculation converts a power gain ratio into decibels (dB). The formula used is: Decibels (dB) = 10 × log10(P1/P2) Decibels = 10 × log10(100) = 20 dB Convert Voltage Gain to Decibels Voltage Gain Convert Example: This calculation converts a voltage gain ratio into decibels (dB). The formula used is: Decibels (dB) = 20 × log10(Voltage Gain) For a voltage gain ratio of 10, the decibels are calculated as: Decibels = 20 × log10(10) = 20 dB Additional Examples: Power Gain to Decibels: If you have a power gain ratio of 1000 (P1/P2 = 1000), the decibels are calculated as: Decibels = 10 × log10(1000) = 30 dB Voltage Gain to Decibels: For a voltage gain ratio of 5, the decibels are calculated as: Decibels = 20 × log10(5) ≈ 14.00 dB If you have any questions or need further assistance, feel free to reach out!
