1 bar = 100kPa (kilo Pascal)
= 100 kN/m2 (kilo newton / square meter)
= 14,7psi
So the standard 200bar filling pressure (around 2 940psi) = 20 000kPa = 20
MPa (Mega Pascal) - about the crushing strength of concrete
Pascal is a measure of pressure = force acting on an area
kg is a measure of mass : 1 Newton is the force that 1 kg produces
Force = mass x acceleration (or gravity)
So in our case 1N = 1kg x 9,8m/s2 and 1kPa = 1kN / 1m2
or something like that.
(Just a little bit more useless information)
