Most countries use metric system (kilograms, grams). The US and UK still use imperial system (pounds, ounces, stones) for many everyday weight measurements.
Mass is the amount of matter in an object and doesn't change. Weight is the force of gravity on that mass and varies by location. We provide mass conversions using standard gravity.
Use grams for small amounts (food, medicine). Use kilograms for body weight and larger objects. Use pounds for US customary weights and some fitness contexts.
