How many pints equals 2 pounds?

Answer 1

The question, as stated, cannot be answered sensibly. A pint is a measure of volume, with dimensions [L3]. A pound is a measure of mass, with dimensions [M]. The two measure different things and elementary dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

As a simple mental exercise consider a pint of air and of water. They will have very different masses.

Answer 2

One pound is equivalent to two cups, so 2 pounds is equal to 4 cups or 2 pints.

Answer 3

It depends on the type of liquid and its density.
