angle of view is only one factor. vertical position of scale is more significant.
and i think we would find that weight is a more accurate method still.
try this wee experiment...
using a jug (whatever jug you fancy) measure 350ml of water. then weigh that water and see how close you were. then try weighing 350g of water.
you can add water 1g at a time if using scales, try doing that with a jug.
