I was at a local restaurant on the weekend and was faced with a perfect example of how the continued use of two distinctly different measurement systems have impacted on the understanding of measurement in general. I asked our server: "How many grams is the 10 ounce steak? I really don't understand all this ounce stuff." She replied "I don't know... hmmm.... ahh... there's about 8 ounces in two cups isn't there? I don't know." She eventually held up her hands demonstrating a 25 cm diameter circle and said "It's big". I replied "Well 'big' is relative, isn't it? I'll have the chicken." greg
