I N S T R U C T I O N S

Input a number in the upper left hand box. (It's the only place for data input).
Click the appropriate number base.
You will then have conversions for all number bases from 2 through 16.
This converter is quite versatile.
For instance, you can convert directly from one number base to another.
Example: To convert 423 from base 5 to base 7:
Input 423 in the input box. Click base 5 and scroll down to base 7 to read the answer which is 221.
You can also read what this equals from base 2 through base 16.

The accuracy of the calculations should be accurate for numbers that are:
253 Binary (a number consisting of 53 "one's".)
9 x 1015 Decimal
1FFFFFFFFFFFFF Hexadecimal
and smaller.

Yes, all the numbers have an increasing amount of leading zeroes from base 2 through base 16. These were purposely put there to make reading all the number bases a little easier.
