    Not quite the right ratio according to this chart.

    by the way, to help your calculation, 1 oz is 28.38 grams. hopefully someday, we will all use metric system.... but probably it won't come in my life time...:+(

    I believe that it has to be weight.
    water weight is constant.
    but roasted coffee bean weight will change depends on light to super dark roast. So I do not think that we can go by the volume.

    1.6265 Grams Coffee per Ounce of Water

    65 Grams Coffee per Liter Water
    (SCAE Standard)
    1 Gram Coffee per 15.39 Grams (Milliliters) of Water
    1.9223 Grams Coffee per Ounce Water

    57.41 Grams Coffee per Liter of Water
    ("Perfect Coffee at Home" Guys, Research-based "Golden Ratio of 17.42")
    1 Gram Coffee per 17.42 Grams (Milliliters) of Water
    1.6977 Grams Coffee per Ounce of Water

    60 Grams Coffee per Liter Water
    (Popular Recommendation)
    1 Gram Coffee per 16.67 Grams (Milliliters) of Water
    1.7744 Grams Coffee per Ounce Water

    It's all certainly still relevant... I typically use the SCAA standard is my starting point with any coffee. Then adjust based on the coffee and my taste.

    My company coffee has one, two, and three bag options. So the ratio can’t be all right.
