Getting the coffee-water ratio right is the key to a great cup of coffee. But coffee measurement is a confusing topic, and “how much ground coffee per cup” doesn’t have a simple answer. Grams to milliliters? Ounces to grams? How many scoops of coffee? What if I like it strong? Do I need a scale? We built this simple coffee calculator to help you figure out the best coffee-water ratio.

Understanding Coffee Measurements
There are two kinds of "cups": the measuring cup you use to make desserts, which holds eight fluid ounces of water, and the coffee cup from which you drink, which holds 6 ounces of coffee. Mugs typically hold a bit more coffee (about 8 ounces). We’ve accounted for those differences as a setting in our coffee calculator.
Using a scale can help you be precise about your coffee-to-water ratio, scoops, measuring cups, and spoons work just fine. The reason coffee professionals use a scale is because coffees vary in density and weight. For example, a scoop of light roast will typically weigh more than the same scoop of dark coffee!
Under the hood, the coffee grounds to water ratio is determined by the brew method, with a 16-1 (water to coffee) ratio as the standard for drip or pour over coffee. To brew stronger, use more coffee grounds or less water.
