How to Convert Decibels to Bels

Decibels, abbreviated dB, and bels, abbreviated B, are logarithmic measures of sound volume. Each time the sound increases by one bel, the sound is ten times louder. The prefix "deci-" means 10^-1, or 0.1, meaning it takes 10 dB to equal 1 B. You might need to convert from decibels to bels if you have multiple volume measurements that you want to compare.
