To convert pressure from in Hg to torr, we can use the following conversion factor:
1 in Hg = 25.4 mm Hg
1 mm Hg = 1 torr

First, we need to convert the altimeter reading from in Hg to mm Hg:
19.00 in Hg × 25.4 mm Hg/in Hg = 482.6 mm Hg

Then, we can convert mm Hg to torr:
482.6 mm Hg × 1 torr/1 mm Hg = 482.6 torr

Therefore, the pressure reading in torr is approximately 483 torr.
