It’s already just past ten o’clock here in Seattle, so I’m assuming a good deal of you parents and teachers have finished your first cup or two of coffee on this National Coffee Day. It’s unclear just how many cups of coffee fueled the scientific minds that finally explained those pesky coffee rings that, depending on your point of view, either ruin or decorate your dining room table.
So, in honor of National Coffee Day here at Math-Whizz we are here to help you try and put that all important question of “how long will this pound of coffee last?” to rest.
- Assume you wake cheerily each morning and grind your coffee to the same fineness.
- One pound of ground coffee = 5.25 cups of ground coffee, 16 tablespoons = 1 cup.
- Using a ratio of two level tablespoons per five ounces of water (what we call a cup of coffee) how many cups of coffee can you expect to enjoy before having to run out to your favorite shop for another pound of beans???
