This applet converts a number in a particular base to its equivalent number in the desired base.For ex:- 101 in the base 2 is equal to 5 in base 10.Just give the values and press enter.Use the following notations for bases greater than 10.10=A(caps),11=B.........15=F,..............35=Z.This applet can convert numbers between bases 2 to 36.That means your present base and desired base must be greater than 1 and less than 37.
