In the United States, barometric pressures are generally reported in inches of mercury (in.Hg)

Question

. On a beautiful summer day in Chicago, the barometric pressure is 30.37 in.Hg
.Convert this pressure to torr
.

Answer 1

To convert inches of mercury to torr, we can use the following conversion factor:

1 in.Hg = 25.4 torr

Therefore, we can convert the barometric pressure of 30.37 in.Hg to torr by multiplying by the conversion factor:

30.37 in.Hg * 25.4 torr/in.Hg = 770.998 torr

So, the barometric pressure of 30.37 in.Hg in Chicago on a beautiful summer day is equivalent to 770.998 torr.
