I use Convexhull tool in QGIS and there are result value :
AREA = 0.0017494390 PERIMETER = 0.1725495172
I thought the result was strange. So, I took a rough estimate of the points through the services provided by other websites and picked out the results.
Other site result :
Area = 17220976.88 m^2 PERIMETER = 17030.657 m
Area value is a difference of 10^10
Perimeter value is a difference of 10^5..
I use "EPSG:4166 - korean 1995" CRS and I also change project properties for units of distance, area. but, there are not any change.
So, I want to know what convex hull units are in QGIS and how to set other setting for ideal value.

The unit of EPSG:4166 - korean 1995 CRS is decimal degree. You need to change the projection of your data to a CRS that uses meter unit. For example, you can use WGS 84 / UTM Zone ## projection with the correct zone number ## in which your data is located in.
The workflow is like this:
- Change the projection of your data to a
WGS 84 / UTM Zone ##with correct Zone number - Use the output data from the first step to add new fields for area and perimeter, and calculate both area and perimeter.
