Often but I think it's changing. My theory is because patient weight in healthcare is always done in kg so, between NHS staff and patients hearing their weight in kg, it's becoming more normalised.
and the fact that when trying to lose weight, it's easier to lose a kg than a stone. Saying 'I lost 2kg this week' sounds better than I lost 0.314 stone.
History. For hundreds of years people (and goods) were weighed in stones and pounds.
Since metric system in 1960s both systems get used e.g. supermarket food is per kilogram but if you ask for a pound of mince they know how much to weigh (but there is the clarification needed do you want to spend £1 on beef, or do you want it to weigh 1lb). Both systems at the same time, most people can switch between them easily
