How do you convert natural log into binary log?

Use the equation.

ln 'x' = log(2) x / log(2) n.

'2' being the binary system of 10101010....

However, it may be easier to understand using base '10'.

lnx' = log(10)x / log(10)'e'

NB This will give a different answer to log base '2' (binary).

NNB Within logarithms you can change the base value tp any other base using the above equation.

Calculators give logs to base '10'(log) and base 'e' (2.71828.....)(ln).

However, you can use any number as a base value e.g. '100' say , or '79' say. providing you use the above eq'n.
