If you know the amount of coffee powder, multiplied by the coefficient 21.33, you know how many ounces of water you need (0.046875 is the inverse coefficient), multiplied by the coefficient 22.2593, you get how many milliliters of water you need (0.04493 is the inverse coefficient).

For example, if you have 1.2oz coffee powder, multiply it by 21.33g, you will need 25.6oz water; 92.6g coffee powder will need 2061CCs water. The amount of coffee powder required can be obtained by multiplying the inverse coefficient with the known amount of water.

If you know the amount of coffee powder, times the coefficient 16, you know how many ounces of water you need (0.0625 is the inverse coefficient), multiplied by the coefficient 16.6945, you get how many milliliters of water you need (0.04493 is the inverse coefficient).

For example, if you have 1.2oz coffee powder multiplied by 16.0, you need 19.2oz water; 92.6g coffee powder requires 1562CCs (1.56L) water. The amount of coffee powder required can be obtained by multiplying the inverse coefficient with the known amount of water.

Comparing the two tables, it is not difficult to find that the so-called brewing of enthusiasts is just a little higher in concentration and heavier in taste. Simple and simple words: one serving of powder, about 16 parts of water.

The picture below is the coffee brewing rate chart of SCAA, which looks a little confused.
