Kilograms and stones are two common units of mass measurement. However, they have different meanings because one is derived from the metric system while the other is an imperial unit. Kilograms are the SI unit of mass, while stones are a non-SI unit of mass.
The choice between using kilograms or stones as a unit of measurement depends on what kind of work you are doing. Kilograms are ideal for construction, weightlifting, and engineering, while stones are useful for gardening and other manual tasks in which soil is being moved around.
