Multiply the size of your French Press in ounces by 0.057. This is the weight of the coffee you should be using, in ounces. I round up. It's an easy piece of math if you have a calculator, and you only have to do it once, ever.

Get a small kitchen scale. Use it for this once, and then you'll be able to eyeball it forever.

Have at it.
