This scale does not measure volume. It claims to measure liquids in fluid
ounces. It does this by assuming your liquid has the same density as water
and any difference in density will result in some error that you have to
live with. It takes the weight in pounds and divides it by 16 and displays
"fluid ounces."

At least it doesn't claim to measure the volume of solids. A cup (8 fl.
oz.) of marshmallows would be a hell of a lot of marshmallows.
