Question: how much coffee to put in a french press for one cup?
Answer: Whatever size of French Press you use, a good rule of thumb is to follow a 1:15 ratio of coffee to water. So for every 1 gram of coffee, add 15 grams of water, which converts to about 3 tablespoon of coffee for every 1 cup of water. Experiment from there to find the ratio that works for your taste.
