Coffee Grams per Cup by Brew Strength Calculator

grams = water_oz · 1.5 · strength_factor / 8.

Compute the grams of ground coffee needed for a given cup of brew at a chosen strength. Standard SCAA Golden Cup ratio is 60 g/L (~10 g per 6-oz cup); the strength_factor (default 1.0) lets you pull weaker (0.7) or stronger (1.3) coffee. Reports grams and tablespoons (≈ 5 g/Tbsp medium grind).
