Question

State two non-SI units of pressure.

✓

Answer

Two non-SI units, which are either of historical interest, or are still used in specific fields are the bar and the torr.
1 bar $=0.1 \mathrm{MPa}=100 \mathrm{kPa}=1000 \mathrm{hPa}=10^5 \mathrm{~Pa}$
1 torr $=(101325 / 760) \mathrm{Pa}=133.32 \mathrm{~Pa}$
[Note : Their use in modern scientific and technical work is strongly discouraged.]
