scale - converting to grams?
Does anyone know how to get the Weigh Of Life scale to show grams? I don't have the manual and I've scoured the internet for hours without results. Currently it shows ounces, and no amount of button pushing seems to change that.
The scale looks like this: http://www.amazon.com/Weigh-of-Life-3084-00-Scale/dp/B00067IYX2 
(mine is an older version with a metal plate instead of glass)
