Outside of universities, I have yet to hear anyone call weight, Newtons. About everyone calls weight kilograms even for commerce. And the kilogram is not a unit of weight in the SI system. Therefore, hardly anyone is using the modern metric system in daily life. The old kilograms-force that is part of the old metric system lives on and seems will never die. Just like the obsolete time scale, GMT. So I'd tone the article down on the popularity of the SI System of Units. — Preceding unsigned comment added by 50.46.167.133 (talk) 00:42, 4 February 2015 (UTC)

No, everybody says "weight" when they mean "mass". Djr32 (talk) 18:20, 5 February 2015 (UTC)
