WWS is on the money....ish. Newton is a unit of force, and a kilonewton is 1000 newtons (like kilometre is 1000 metres).
To give you an idea, 1 kN is the weight of a 100kg mass, or a big bloke hanging. 1N is equivalent to the weight of a 100g mass, or a king size Mars Bar.
You might also see stuff rated in "daN", meaning decanewton. This is 10N, or about the force required to hold a 1kg mass. |
