To convert from Hexidecimal to Decimal:

Run the Windows Calculator, open the View menu and select Scientific.



Click on the "Hex" radio button and type in the hex lot number. There is no need to type the leading zeros, or to type in a "0X" prefix, which just indicates that this is a hex number.



Click on the "Dec" radio button to perform the conversion. From this, we find that the (decimal) lot number for Spear Point is 61.



To convert from decimal to hexidecimal, just reverse the process:
- Click on "Dec" and type in the number
- Click on "Hex" and the number is converted.
