The Vietnamese grading system is an academic grading system utilized in Vietnam.It is based on a 0 to 10-point scale, similar to the US 1.0-4.0 scale.. Typically when an American educational institution requests a grade-point average calculated on the 4 point scale, the student will be expected to do a direct mathematical conversion, so 10 becomes 4.0, 7.5 becomes 3.0, etc.

Units of elevation or depth should be given by symbols, immediately after the digits. [b] Elevation below zero-level reference or depth above reference level should be indicated by a minus sign − (U+2212). Examples: 50°40′46″N 95°48′26″W 123.45m; 50°03′46″S 125°48′26″E 978.90m
The atomic units have been chosen to use several constants relating to the electron: the electron mass, the elementary charge, the Coulomb constant and the reduced Planck constant. The unit of energy in this system is the total energy of the electron in the Bohr atom and called the Hartree energy. The unit of length is the Bohr radius.
Deci-(symbol d) is a decimal unit prefix in the metric system denoting a factor of one tenth. Proposed in 1793, [ 1 ] and adopted in 1795, the prefix comes from the Latin decimus , meaning "tenth". Since 1960, the prefix is part of the International System of Units (SI).
Note: map situation has now changed due to internal migration.
