Are there 60 ounces of liquid in 2.5 pounds?

No: there are 40 ounces. 1 pounds = 16 ounces. Thus, 2.5 pounds = 2.5 * 16 ounces = 40 ounces Note that because different liquids have different densities, the question cannot be answered without more information if referring to fluid ounces (units of volume) rather than ounces (units of mass).

Why cant you convert fluid ounces to pounds?

Why can't you use fluid ounces and pounds interchangably?

Fluid ounces is a measurement of volume and pounds are a measurement of weight. It isn't possible to use fluid ounces and pounds interchangeably because different liquids have different densities. Meaning that 100 fluid ounces of water doesn't weigh the same as 100 fluid ounces of vegetable oil. You can test this by pouring a little vegetable oil into a small glass of water. The oil "floats" to the top because it is not as dense as water. Here is another interesting fact: liquids have different volumes depending on the temperature of the liquid. A glass of water at 36 degrees Fahrenheit has a different volume than the same glass of water where the water is 100 degrees Fahrenheit.

How many cups are in 2.5 dry ounces?

It depends heavily on what you are measuring. Ounces is the measurement of weight and since dry goods have very different weights, there is no universal table. 2.5 oz of walnuts is going to be a lot less than 2.5 oz of rice since their densities are different.
