In the top section you can convert base ten numbers to other bases, from base two through base sixteen. In the next part you can convert numbers in bases two throught sixteen back into base-ten numbers. Note: This page does not check for invalid input. NaN stands for not a number; if you get this check your input.
In this part enter a number of the correct base in just one of the boxes. The page will convert it to the other bases for you. Note: Again there is no check for invalid input, this is the users responsibility.
