Kilogram is not the metric unit of weight, it’s mass. 1 liter of water has mass of 1kg. 1kg of water weighs 9.81 newtons - at least on earth. Newton is the metric unit of weight.
Comment on Tiddies are nice but the metric system is better
polotype@lemmy.ml 2 weeks agoSee, 1 liter isn’t 1kg , 1 litre of water weighs 1kg. There’s the difference, and as such there is no reasin for 1 litre of water to weigh 1 gram.

9.76N to 9.83N depending where you are, if you want to be super pedantic.

“Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2.”

Also depends on how much mass the weighed object has so not constant based on of the position alone. But 9.81 or 9.8 is generally accepted as the acceleration due to gravity on earth. F=Gm1m2/r^2 if you’d like to be extra specific.

You don’t seem to have understood the question.
1 kilogram is 1000 grams. Kilo isnused in place of the 1000.
1 litre of water weighs 1000 grams. Why couldn’t it be 1 litre of water is 1 gram?

Because units less than a litre are so common. 2ml of syrup, 4dl of flour, 12cl of wine, 0.5l of beer, etc. But things you measure by mass rarely go below 1 gram (in day-to-day life at home). Candy bar is 50g, a packet of cheese is 200g, a chunk of meat is a kilogram. Besides, most people just call it “a kilo” so the common units in the spoken language are “a kilo” when talking about mass and “a litre” when talking about volume
