Vietnamese units of measurement (Vietnamese: hệ đo lường Việt Nam) are the largely decimal units of measurement traditionally used in Vietnam until metrication. The base unit of length is the thước ( chữ Nôm : 𡱩 ; lit. "ruler") or xích ( chữ Hán : 尺 ).
Metric units are units based on the metre, gram or second and decimal (power of ten) multiples or sub-multiples of these. According to Schadow and McDonald, [ 1 ] metric units, in general, are those units "defined 'in the spirit' of the metric system, that emerged in late 18th century France and was rapidly adopted by scientists and engineers.
The Chinese sheng (Chinese: 升; pinyin: shēng), called sho in Japan and seung in Korea, also called Chinese liter, is a traditional unit of volume in East Asia.It originated from China and later spread to Japan, the Korean Peninsula, Vietnam and other places. [1]
In the early metric system there were two base units, the metre for length and the gram for mass. The other units of length and mass, and all units of area, volume, and derived units such as density were derived from these two base units. Mesures usuelles (French for customary measures) were a system of measurement introduced as a compromise ...
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.

All modern roads and railways are measured, built and signposted in the metric system. All the imperial speed limit signs were replaced within 3 days in 25 August 1984 to 27 August 1984 upon enactment of new traffic law, with a temporary territory-wide speed limit of 50 km/h in force within that 3 days, while all remaining road signs were gradually replaced within the following 3 years.
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic . Each prefix has a unique symbol that is prepended to any unit symbol.
