Conversion of Natural Logs to Base-10 Logs.

Some business calculators have natural logarithm functions instead of base-10 logarithms. Many scientific calculators have both. Natural logarithms use the number (e = 2.7183...) as their base instead of the number 10. The natural logs and natural antilogs can be converted to base-10 counterparts as follows:

Natural logs usually use the symbol Ln instead of Log.

Natural antilogs may be represented by symbols such as: InvLn, Ln^(-1), e^x, or exp.

To convert a natural logarithm to base-10 logarithm, divide by the conversion factor 2.303.

To convert a natural antilog to a base=10 antilog, multiply by the conversion factor 2.303 before taking the natural antilog..
