One gram is about the mass of a house fly, while a kg approximately equals 3 pounds. Technically, both could measure a ship's anchor, but usually the kg would be the better unit to use.
The mass of an anchor is 40 kg. 40 g would be too light for an anchor.
g
A unit of mass is measured in kilograms (kg) or grams (g).
The weight of a single banana would be measured in grams (g). A bunch of bananas would be measured in kilograms (kg).
You can measure wheat by kg [kilograms] or g {grams}
in kg for larger, heavier objects, but g for smaller lighter objects
Weight is measured in kg wt which equals to g newtons. g - acceleration due to gravity at that place.
A small correction. Force is measured in newton and in kilogram weight too. 1 kg wt = g newton Here g is the acceleration due to gravity at that place. That is why when we ask some one to give his weight he would say only the kg for example 50 kg. In the query 'weight' is there. So as we say 50 kg then it implies that 50 kg wt. Kilo gram is the unit of mass and not for force. Only kg wt is the unit of force
Mass and weight are measured in grams or kilograms.
Mass is typically labeled in units of kilograms (kg) or grams (g).
When we say "number of g forces" the g we are typically (not always) talking about is the average overall Earth of around g = 9.81 N/kg or m/sec^2 (See NOTE) So, for example, if a jet jock pulls 2 g's in a hairy vertical climb, he's pulling 2g = 19.62 N/kg on his body. And if his mass is m = 100 kg, that means his effective weight is W = m(2g) = 1962 Newtons. Bottom line. g forces are measured as the number of average g's. NOTE: N/kg = kg.m/sec^2//kg = m/sec^2 which is to say they are equivalent units.
Food in the UK is measured in metric: Liquid - ml Solids - g & kg
