If you find a simple calculator valuable in the kitchen, then you'll find the Kitchen Calc Pro invaluable. It not only adds, subtracts, multiplies, and divides, but it also converts cups to tablespoons and ounces to grams, as well as performing all manner of other calculations.
In addition, the Kitchen Calc Pro has a digital timer that can run while you adjust recipe proportions or serving sizes or calculate anything else. The numbers are large, and the calculator fits into a plastic sleeve that keeps it clean in food-prep battle zones. Produced by aptly named Calculated Industries in Carson City, Nevada, and available in specialty cookware stores, the countertop Kitchen Calc Pro (model 8304) sells for about $40; a smaller handheld model costs about $25.
