Answer 2

The International System of Units (SI) is the basis of the modern metric system. All SI units can be derived from the seven fundamental SI units.

Ranges of specific units are indicated by positive or negative multiples of powers of ten (e.g. 102, 10-2, etc.).

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

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

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

A standardized prefix system indicates fractions and multiples of metric units (e.g. milli-, mega-).
