# How many tablespoons of butter are in a tablespoon of butter?

The title may sound silly, but the question is serious:

When I buy butter, the package says Net Wt. 16oz, and I trust this because the authorities regulate such things.

Inside the package, each stick is divided evenly into 8 tablespoons. Now, although a fluid ounce of water might weigh almost exactly a 1/16 of a lb., butter is like 80% fats. There's no way a fluid ounce of butter (exactly 2 tablespoons) weighs 1/16 of a lb.

So, how many tablespoons of butter are there in a "tablespoon" (per the package marking) of butter?

• Pretty sure this is just the density of butter in fl.oz./oz.

• 1 fluid ounce of water weighs 28.4131g. 1 tablespoon of water weighs 17.7582g. I am not sure how this matches your calculations.

• The only way I can make sense of this question is if the 16oz package contains 4 sticks. Is that the case, or have I misunderstood? That's not the way butter is packaged in my country. Oct 6 '21 at 1:19
• @DawoodibnKareem the whole "stick of butter" concept is an American thing. Here it's a block of 250g with approximate 50g markings on the wrapper Oct 6 '21 at 8:18
• Makes sense. I've seen recipes that call for "1 stick of butter" or "1/2 stick of butter" or whatever, and had no idea how much that is. Oct 6 '21 at 20:26

16 fluid ounces of water do not weigh one pound, they weigh a little more (about 1.05lbs), because the US fluid ounce is not based on water, unlike the liter.

You are correct that 16 weight ounces of butter aren't equivalent to 16 fluid ounces either, but they're pretty close. 1 fluid ounce of butter is 99% of one weight ounce. So if you're getting 16 weight ounces of butter, you're actually getting an extra 1% over 16 fluid ounces.

And who's going to complain about 1% extra butter?
