they're all different conversions of each other. One is electrical current, one is parts per million, one is total disolved solids.

The guy above me posted a good link for converting, but if you want an explanation, this is a decent link

Ok but how do you apply those values to your grow. Sorry to be so noobish I normally use soil so this is chinese to me

There are really 2 values and they are only marginally related. You want to keep pH between about 5.5 and 6.5. Don't get on the pH roller coaster by checking and adjusting many times a day, do it once a day. The other value is an index of your nutrient concentration whether in EC or ppm. There I recommend you follow the feeding schedule of your nute manufacturer. After you have set the res, measure ppm and that becomes your baseline until the schedule calls for a change and you change the res.
