Arrhenius equation

I have a question about this: when you write the arrhenius equation expressed in terms of logarithms to the base 10 it looks like this: logk=logA - (Ea/2.303RT), where Ea is activation energy. From where does the 2.303 come? I've searched in many books but I didn't find out from where it comes. Merry Christmas to all and any help would be apriciated.

It is introduced to convert natural logarithms (taking which reduces the exponential function to the value to its exponent) to logarithms to base 10.
