For future use:

Digital kitchen scales that switch from U.S. to metric measurements start at about $ 20 on Amazon.com. They weigh in Grams and fractions of an ounce up to 5 kg (5000 gm) / 11 lbs. Most U.S. measuring cups are marked in U.S. and metric volumes.

thanks for the information - I often have trouble converting to cups and oz -

American cups are 8 ounces. English cups are 10 ounces.

Even the Tablespoon is different. In Australia it equals 4 teaspoons (20 ml), in the U.S. it equals 3 teaspoons (14.8 ml).
