You can determine if your location is east or west longitude by looking at the numerical value of your longitude coordinates. If the value is positive (+) then you are in the eastern hemisphere, indicating east longitude. If the value is negative (-) then you are in the western hemisphere, indicating west longitude.
The preferred format for latitude and longitude values in ArcGIS is decimal degrees. This format expresses coordinates as a single value in degrees, with positive values for north latitude and east longitude, and negative values for south latitude and west longitude.
The two points can be distinguished using different longitude coordinates. The point in North America would have a negative longitude value, while the point in China would have a positive longitude value due to their respective locations in relation to the Prime Meridian (0 degrees longitude). This distinction in longitude values would help identify the specific locations of the two points.
The Prime Meridian is defined as Zero Longitude. Any longitude that you feel is "close" to zero is close to the Prime Meridian.
The distance east or west from the Prime Meridian is measured in degrees, with 360 degrees in a full circle representing the Earth's circumference. The Prime Meridian itself is set at 0 degrees longitude, so any location east of it will have a positive longitude value, while any location west of it will have a negative longitude value.

To read latitude and longitude degrees, start with the latitude value, which indicates the north-south position and ranges from -90 degrees (South Pole) to +90 degrees (North Pole). Next, look at the longitude value, which indicates the east-west position and ranges from -180 degrees (International Date Line) to +180 degrees (Prime Meridian). The combination of these two values provides a specific location on the Earth's surface.
All meridians of longitude join the Earth's north and south poles. So they all have the same length ... half of the Earth's polar circumference, or about 24,800 miles.
The difference in longitude between two places is:Absolute value of [ (one longitude) minus (the other longitude) ].The easist way to calculate it is as follows:--> If both points are in the same hemisphere(both east longitude or both west longitude):-- Subtract the smaller number from the larger number.--> If the points are in different hemispheres(one east longitude and one west longitude):-- Add the two numbers.-- Subtract the result from 360.

The value of zero is zero. Zero is always going to have a value of zero.
The spherical Earth has 360° of total longitude, divided into 180° east of the Prime Meridian and 180° west of the Prime Meridian.So the highest value for longitude is 180° (this is nominally the International Date Line, and 180° E is the same meridian as 180° W).
