DESCRIPTION
percentage between 0% and 100%.
This is the common unit of measurement for
air pressure in the United States. It refers to
the length of a standard column of mercury
(a liquid metal) that can be pushed up by the
ambient air pressure. Standard pressure is
approximately 29.92 inHg
One knot is equivalent to one nautical mile
and is sometimes used to indicate wind
speed.
An acronym for "Liquid Crystal Display."
This is a common type of display screen used
in televisions, computers, watches, and digital
clocks.
The unit of illuminance
intensity of illumination on a
in the SI system.
See HECTOPASCALS.
This is similar to inches of mercury, except
expressed in millimeters. Standard pressure is
approximately 760 mmHg.
National Institute
Technology. A United States institute that
keeps very accurate time using atomic
clocks and provides and internet-based
service to accurately set device clocks.
Relative air pressure is the absolute air
pressure compensated for the altitude of the
barometer. The result is what the air pressure
would be at sea level.
Thin-Film-Transistor, a type of LCD screen.
The ultraviolet index or UV-Index (UVI) is an
international standard measurement of the
