2. Official measurement units are the units specified in Article 7 and Article 8 of this Decree.

3. Other common measurement units are the units that are not mentioned in clause 2 of this Article, including traditional units and other measurement units.

Article 3. Rules for the use of measurement units

1. Official measurement units are compulsory in these following cases:

...

b) On the measurement instruments used for the examination, inspection and other public services;

c) On the labels of quantitatively prepackaged products subject to examination according to the regulations in the Ordinance on Measurement;

d) In the manufacture, trade, import of measurement instruments subject to examination according to the Ordinance on Measurement.

2. Other common measurement units may be used in the activities other than the cases specified in clause 1 of this Article.

The conversion from a common measurement unit into an official measurement unit is expressed according to Article 4 of this Decree.

3. The state shall encourage organizations and individuals to use the official measurement units according to the regulations in this Decree.

Article 4. The conversion from the common units into the official measurement units

1. The conversion shall not lead to any change in the value of quantity.

2. The conversions from other common measurement units into official measurement units are regulated in Annex I enclosed herewith.

...

3. When expressing the values, the common quantities, values and units shall go after the official ones and shall be put in the brackets.

Ex: One (01) tael of gold shall be expressed as follow: 37,5 g (1 tael).

Article 5. The application of the International Agreement

If the Socialist Republic of Vietnam accedes an International Agreement on measurement units whose regulation is different from this Circular, such International Agreement shall prevail.

Article 6. The expression of official measurement units

The expression of measurement results, the conversion from a common measurement unit into an official measurement unit shall be in accordance with the regulation in Annex II enclosed herewith.

c) Compound prefix names or symbols are not permitted for the formation of decimal multiples or submultiples of an official SI unit.

Ex: nanometer: 1 nm or 10^-9 m, not: millimicrometre: mµm.

Where nano is name; n is its symbol and 10^-9 is its multiplying factor.

Note: This rule does not apply to the kilogram. For historical reasons, the name “kilogram” contains the prefix name “kilo” to the name “gram”. Thus, decimal multiples and submultiples of the kilogram are formed by attaching the SI prefixes for gram.

Article 8. The measurement units outside the SI (non-SI units)

The measurement units outside the SI include:

ANNEX II

WRITING OFFICIAL UNITS OF MEASUREMENT
(Enclosed with the Decree No. 134/2007/NĐ-CP dated August 15, 2007 by the Government)

The official measurement units shall be written as follows:

1. Names and symbols of a unit shall be printed in a consistent style (only name or only symbol of the unit).

Ex: Kilometre/hour or km/h, not kilometer/h or km/hour.

2. Names of units shall be printed in upright type and start with a lower-case letter, including the units derived form proper names, except for Celsius degree.

Ex: metre, second, ampere, kelvin, pascal,…

3. Names of units shall be printed in upright type and start with a lower-case letter, except for the litre (L)

Ex: m, s…

...

Ex: A, K, Pa…

4. The official measurement units must not be attached any affixes or other symbols.

Ex: “We” must not be used as a symbol of power instead of W.

5. Multiplication must be indicated by a dot (.).

Ex: The unit of resistance power is metre kelvin per watt: m.K/W (where m is the symbol of metre), apart from millikelvin per watt: mK/W (where m is the SI prefix milli)

6. Division is indicated by a horizontal line, by a solidus (oblique stroke, /) or by negative exponents.

Ex: or m/s or m.s^-1 for metre per second.

When several unit symbols are combined, the symbols shall be put in brackets or negative exponents shall be used.

Ex: J/(kg.K); m.kg/(s³.A) or J.kg^-1.K^-1; m.kg.S^-3.A^-1.

...

numerical value and the unit symbol.

Ex: 22 m, not 22m or 22 m.

Note 1: The symbol of Celsius degree shall not include any space between the degree symbol (^o) and the Celsius symbol (C).

Ex: 15 ^oC, not 15^oC or 15 ^oC.

Note 2: The symbol of plane angles that is ^o (degree); ¢ (minute); ² (second) shall not include any space between the quantity value and the symbol (^o); (¢); (²).

Ex: 15^o20¢30¢¢,not 15 ^o20 ¢30 ¢¢ or 15 ^o20 ¢ 30 ¢¢.

Note 3: When express quantity value by operation, the unit symbols shall be preceded by the numbers or the brackets containing the numbers of the operation.

Ex: 12 m – 10 m = 2 m or (12-10) m, not 12 m – 10 = 2 m or 12 – 10 m = 2 m.

12 m x 12 m x 12 m or (12 x 12 x 12) m, not 12 x 12 x 12 m.

...

Note 4: Comma (,) shall be used as the decimal mark of the quantity value, not point (.)

Ex: 245,12 mm, not 245.12 mm
