Just how much ground coffee do I need for x amount of coffee?

a. Whatever seems right to you.
b. It may change slightly from coffee to coffee and according to freshness and varietal.
c. What the Specialty Coffee Association of America (SCAA) has to say:
A cup is defined as 6 ounces of water before brewing. This will produce 5.33 ounces of brewed coffee. Or 125 ml & 110 ml for Euro style coffee makers
The SCAA defines 10 grams or .36 oz per cup as the proper measure for brewed coffee if using the American standards. If using Euro standards the measure is 7 grams per 125 ml.
To further confuse things I will add a few more measures:
3.75 oz per 1/2 gallon
55 grams per liter
2.25 gallons per 1 lb.
If you want to know more check the SCAA's web page at www.scaa.org.
d. The easy answer for most home coffee brewing is 2 Tbs. per 6 oz of water. A standard coffee measure should be 2 Tbs (1/8 cup) . Be warned some coffee measures deviate from the 2 Tbs. standard. Some are even as small as 1 Tbs.

It needs to be pointed out that some coffee pot manufacturers deviate from the 6 oz per cup standard. You should check the total water capacity of your pot before assuming that the pot will be measured in 6 oz cups.

If you have a pot that is overflowing the basket even after checking the cup size the chances are that you are either grinding too fine and clogging the filter or your coffee pot manufacturer has decided to make their filter basket a little smaller than normal. If the issue is a small basket your best bet it to figure out how much coffee the basket will hold and add water accordingly. For example, if your filter basket only holds 8 scoops (16 tbsp) without overflowing fall back to 48 oz (8 x 6 oz cups) of water.

Ultimately the amount of coffee to use is a personal taste but I highly recommend at least starting with the standard and adjusting from there and don’t forget as you move toward more water and less grounds you will extract more off flavors. Most people that say they don’t like strong coffee mean they don’t like bitter coffee and weak coffee actually has more bitter compounds. You can always add hot water to weaken coffee. Weak coffee if just weak coffee and can not be fixed.

THE REAL ANSWER

is figure it out yourself via trial and error.
As a guideline: for a medium roast coffee, at a medium grind: 1 Tablespoon grounds for each 6oz cup of water will give you a medium brew.
I do this with Starbucks pre-ground columbian coffee. It works perfectly. I will say that if you buy a cup of starbucks house in their store it is definitely stronger than 1T:6oz ratio.
This 2 Tbs per 6oz is crazy; it will make a strong brew. Nothing wrong with that, but it's strong and thick. 

So totally agree!

"figure it out yourself via trial and error"
It is all a matter of PERSONAL TASTE! I don't want anyone else dictating to me what my personal taste should be (in coffee or anything else). You have to be awfully anal-retentive to believe that there should be exactly one 'best' way that everyone should brew their coffee. That applies to every aspect of the process. Which coffee to use, how much coffee to use, whether to use  flavorings (either in the grounds or as post-brewing additives), whether to add sweeteners (sugar or artificial), whether to add 'lighteners' (milk, cream, or other), and so on.
Asking someone else to define how YOU should prefer (and brew) your coffee is like asking someone else what color you should like or who you should marry. It's PERSONAL PREFERENCE.

Sometimes you do need a standard, a starting point.

Our office is in the middle of a coffee war - how strong or how weak to brew? In this case, personal taste and trial and error is not serving us well, but referring to a standard and accepting everyone's personal tastes as somewhere on the weak - average - strong continuum will help keep the peace. 

Office war

Just make it strong as possible and everyone
Can weaken(add hot water) to taste

QA and Testing Tutorial

I wanted to thank you for this great blog! I really enjoying every little bit of it and I have you bookmarked to check out new stuff you post.

coffee measure

Well I've been using 1 heaping tablespoon per cup and it works for me. If I care for a stronger cup then I add a bit more. 

How much coffee to use for a 6oz Cup of coffe?

In the original entry of this blog it says: " the SCAA defines 10gram or .36oz  as the proper mearsure for brewed coffee".  Since 1 TBLS = 1 ounce,  that would  meean .36 tablespoon per 6oz cup of coffee.  Which means 2 Tablespoons of coffee would make six 6oz cups of coffee.    So is the coffee manufacturers just trying to fool us into thinking that we really need 2 TBLS to make one 6 oz cup of coffee so they sell more coffee grounds?  or what am I missing here?  I actually use more like two TBLS per 5 cups.

Weight to volume

Actually, 1 oz is TWO tbsp, but only for water and similar liquids. (It doesn't even hold true for alcoholic liquids, much less oils or solids). Coffee is FAR less dense than water, so 1 tbsp is, in fact, 1/4 to 1/2 ounce by weight, depending on the grind (finer grinds pack tighter and will weigh more). For a medium grind, there are about 3 tbsp per ounce.

How much coffee do I need

Just to show everyone that I need a life. I decided to measure the water in the carafe with a liquid measuring pyrex cup.  To my amazement---the carafe is designed for 6 oz cups, not the real measure of 8 oz.  Based on this scientific information, the type and quality of coffee used. I decided to use 2.5-3 tablespoons for each 12 0z or 6 cups of coffee.   Because I'm so brilliant, I try to use the best whole bean coffee, if one is using dark brew one might consider reducing the coffee.  Hum! wonder what brilliant experiment I can perform tomorrow or should I go shopping?
 
 

ounces vs. fluid ounces

You are mixing incompatible units, although I can see why. 
Grams are measures of weight (well, mass), which implies that the SCAA is using ounces in the sense of weight as well.  Tablespoons are measures of volume.  There are two tablespoons in a fluid ounce (again, volume), and one fluid ounce of water weighs one ounce—but dry coffee grounds are much lighter than water, so an ounce of coffee grounds by weight will be more than two tablespoons.  No one is fooling us, you're just trying to make a conversion that can't be made without knowing the density of coffee. 
Also, two tablespoons for five cups is insanely weak coffee.
