About this calculator
The antilogarithm is the inverse of a logarithm: log_b(antilog) = log_b(b^x) = x. Useful for converting log-scale measurements (decibels, pH, magnitudes) back to linear values. 10^2 = 100, 10^pH = hydrogen ion concentration, etc.
Frequently asked
It's the same math (b^x). "Antilog" is just the historical name when used as the inverse of a log table.
