Most digital scales these days will switch easily between grams and kilograms, as well as pounds and ounces, so don’t panic if you think you’ve accidentally bought “a metric scale”—chances are that there will be a button marked “Unit” that allows you to switch easily between imperial units and metric ones. Check before you buy how precise the scales are—some let you weigh in increments of 0.05 ounces, while others go up or down by 0.1 ounces. If you regularly weigh out small amounts of ingredients, this is important. It’s also worth checking the weight limit too. If you regularly cook large joints of meat, a scale that tops out at 11 pounds might not be enough for you.
