No, the fluid ounce weighs 1.232 grams more.
The same as a stick of butter weighs anywhere - 4 oz.
There is 12 tablespoons in 6 oz of butter.
From the related question (see below) it can be seen that for butter 1 fluid ounce has a mass of 1 ounce. So (50 grams) / (28.35 grams/oz) = 1.76 oz, which for butter is 1.76 fluid ounces.
It is the same.
A fluid ounce is a unit of volume and a (dry) ounce is a unit of mass or weight, however a fluid ounce of water does weigh 1 ounce at 4 degrees Celsius.
It depends on the substance
That depends. Are you talking about 18 fluid oz. of peanut butter? If so, that is 2 & 1/4 cups (a cup is 8 fluid oz.). If you are looking at jar of peanut butter that reads 18 oz., you are going to actually have to scoop the peanut butter out into measuring cups to find out. The 18 oz. in this case is a weight measurement (not volume). The amount of cups you get will vary base on the specific recipe used to make the peanut butter.
That is 4 fl oz.
1 fluid ounce = 29.573 ml
If you are wanting to know the measure in WEIGHT then 16oz in 1lb However, if you are wanting to know the VOLUME, then there are 10.67fl-oz in 1 pound of honey.
== Fluid ounces or dry ounces?== Exactly the same as the ounces in a pound of feathers, which is 16 ounces to the pound. Unless you are talking about fluid ounces. An 18-oz. jar of Skippy, for example, contains 30 tablespoons (tbsp.) of peanut butter. That's the same as 15 fluid ounces. So, doing the arithmetic, one pound of Skippy peanut butter is about 13.33 fluid ounces.
