Question

which one of the following pressure unit represent the least pressure ?

Answer 1

1mm of Hg=133.41N/m². 1N/ mm²=10⁶ N/m² 1kgf/cm²=98.1x 10³ N/m². Hence Least pressure units are 1 millibar. 5.0.

I hope my answer help to u and right

Answer 2

One of the following pressure unit representing the least pressure

is Millibar.

Millibar = 102 Pa.

The pascal (Pa) is the SI unit of pressure, which is defined as a force of one Newton per square metre. The following is the formula for converting between atm, Pa, and torr: 101325 Pa = 760 torr = 1 atm
