Even though it uses 3d6 to roll abilities, the d20 system uses 22 point ability stats for the common range. That's 20 points between least (3) to greatest score (22). This is easily converted.
First, Star Frontiers uses 5 point increments on stat bonuses and the like, so it's easy to convert and use the 1 point increments of the d20 system, because 1 point from d20 equals 5 points from Star Frontiers.
When rolling, in
Star Frontiers, you are looking for the lowest roll for a success, whereas, in d20, you are looking for the highest roll. Thus when you want a 20 or less to hit in Star Frontiers, you want a 17 or better in d20.
Roll the ability for your character or compare your existing character's abilities to the following table to convert it to the target system:
