The units are divided into two classes: base units and derived units. The SI was established in 1960 and is based on the metre-kilogram-second system rather than the centimetre-gram-second system. The International System of Units (abbreviated SI from the French Système International d’Unités) is the basis of the metric system. International System of Unitsthe basis of the metric system SI, from the French Système international d’unités metric measurements derive from seven base units and multiples of ten.Newtonin the International System of Units, the derived unit of force the force required to accelerate a mass of one kilogram by one meter per second per second symbol: N.

pascalin the International System of Units, the derived unit of pressure and stress, equal to one newton per square meter symbol: Pa.PressureThe amount of force applied over a given area divided by the size of the area.barometeran instrument for measuring atmospheric pressure.A standardized prefix system indicates fractions and multiples of metric units (e.g.

The conversion between atm, Pa, and torr is as follows: 1 atm = 101325 Pa = 760 torr.

The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter.

Pressure-the effect of a force applied to a surface-is a derived unit, obtained from combining base units.

Ranges of specific units are indicated by positive or negative multiples of powers of ten (e.g.

All SI units can be derived from the seven fundamental SI units.

The International System of Units (SI) is the basis of the modern metric system.
