MySQL's CONV(~) method converts the input number from one base to another and returns it as a string.

Parameters

1. N | number

The number to convert.

2. from_base | number

The base to convert the input from. Range 2 - 36.

3. to_base | number

The base to convert the input to. Range 2 - 36.

Return value

String representation of the input number converted to the base specified by to_base.

Examples

To convert 17 from base 10 to base 2:

SELECT CONV(17, 10, 2);
+-----------------+
| CONV(17, 10, 2) |
+-----------------+
| 10001 |
+-----------------+

Although it is difficult to see, the returned output is a string.

To convert from hexadecimal (base 16) to base 10:

SELECT CONV('E', 16, 10);
+-------------------+
| CONV('E', 16, 10) |
+-------------------+
| 14 |
+-------------------+
