Weight Converter
The weight converter handles all common mass and weight units — metric (kg, g, mg, tonne) and imperial (lb, oz, stone) — with live results as you type. Weight conversions come up constantly in cooking, travel (baggage limits), fitness (body weight), and shipping. The reference table shows everyday objects at familiar weights to help you build intuition for unfamiliar units.
