Just so you will know next time corazon ... jennyema was right about the volume and weight of water being equal because it's density (Specific Gravity) is 1 thus 1 oz liquid = 1 oz volume - hence the famous saying, "A pint's a pound the world around".
Okay, protecting myself in advance from the physicis and chemistry majors in here:
The SpG of 1 is for pure water at 60-F. The actual weight of water will change with temperature and the amount of dissolved minerals in the water. However, unless your digital scales are accurate to 4 decimal places - 8 liquid oz of water measured in a standard kitchen measuring cup at room temp will weigh 8 oz.
