unit of variation; plus or minus that percentage from the stated value
Pascal – the International System of Units (SI) unit of pressure, stress, and tensile strength; it is a measure of perpendicular force per unit area; ie equivalent to one Newton per square meter, or one Joule per cubic meter.
Kilo-Pascal (1000 Pa)
Newtons – the International System of Units (SI) unit of force. One DecaNewton (daN, 10N) is roughly equivalent to the non-SI unit of force, kgf (the force exerted on 1kg of mass by standard gravity, 9.80665 m/s2) i.e.1 kgf= 9.80665N
Kilo-Newton (1000 N)
grams per square meter; unit of weight (1g = 0.001Kg); the force of gravity on matter
metre; mm – millimeter (0.001m); units of length
