I can't give you hard numbers, but I can tell you that surface IS important. They are calibrated for a "matte" type surface, so if you try using them on say a tile surface they can be WAY off. I regularly use one while cooking and while they work wonderfully for most foods, they are horrible when dealing with say a pot of water.
