Give information for the units of pressure $torr$ and $bar$.

(N/A) The unit $torr$ is named after Evangelista Torricelli. It is defined as $1 \ torr = 1/760$ of a standard atmosphere. Thus,$1 \ atm = 760 \ torr$. Since $1 \ atm = 1.01325 \times 10^5 \ Pa$,we have $1 \ torr \approx 133.322 \ Pa$.
The unit $bar$ is a metric unit of pressure,but not part of the $SI$ system. It is defined as $1 \ bar = 10^5 \ Pa$. This unit is commonly used in meteorology and industrial applications because it is very close to the standard atmospheric pressure $(1 \ atm = 1.01325 \ bar)$.
