I saw this in CHEFS catalog. It's a measuring cup and scale all in one. Here's the description:
With this modern invention, both weight and volume can be measured and units can be converted into recipe requirements. Multiple function scale includes a preprogrammed volume conversion for water, milk, oil, sugar and flour. Use the auto zero reset function to measure each ingredient that is added or the total weight using the add & weigh function. Weighs up to 6.6-lb./3kg. Volume capacity is 4-cup/3L measuring in cup, ml, liter, fl. oz, gm and lb. Features auto shut-off for food prep convenience. Long-life lithium battery included. Hand wash. 10"L x 7"W x 6"H
I think it would be a neat thing to have if it worked well, but so far I've not read any reviews. It's $34.95, and here's the link.
