Longitude is an angle. It can be described in any common unit of angle measure.
Historically, it's degrees/minutes/seconds.
Lines are completely irrelevant, and only serve to confuse people.
You would not ask "What measurement is used to express lines on a ruler ?"
You would ask "What is the unit of measurement for length ?"
Longitude lines are the North/South lines that separate the earth in 15 degree sections. They are used for navigation.
Kilograms are used to express the metric measurement of mass.
You would use angular degrees or angular degrees plus minutes and seconds.
The labeling of latitude and longitude lines as S and E on a map of Australia is a common convention to indicate the direction in which the lines are measured. The S stands for southward measurement along the lines of latitude, while the E stands for eastward measurement along the lines of longitude. This convention is used to maintain consistency in map orientation and navigation.
Degrees.
The lines of longitude are represented in green on most maps and globes.
it is longitude
Longitudinal lines, also known as meridians, are imaginary lines that run from the North Pole to the South Pole and help to divide the Earth into the Eastern and Western Hemispheres. These lines are used to measure degrees of longitude east and west of the Prime Meridian, which passes through Greenwich, England. They help to establish time zones and navigate locations on Earth.

It's the lines of longitude which are used to define time zones, not lattitude.
They are used to locate a certain place on a map.
