The unit used to measure barometric or air pressure

Explanation:

Torr is also used to measure barometric pressure, originally being equal to millimeter of mercury, but later it is defined as slightly different. Some SI units are also used such as hPa (hectopascal), kPa (kilo pascal) or mbar (millibar).

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
