Are you searching for a complete chart of mass measurement units to easily convert units quickly and accurately? In this article, Software Tips shares with you the most detailed and comprehensive chart of mass measurement units.

I. What are Mass Measurement Units?
Mass measurement units are units used to measure the mass of materials or objects.
Commonly used worldwide, and particularly in Vietnam, the most prevalent unit of mass measurement is the kilogram (KG) – Also the fundamental unit in the International System of Units (SI) and globally accepted. Besides the Kilogram, there are various other units used in agriculture, industry, and commerce such as Ton, Tạ, Yen, Hectogram (hg), Gam (g)...
II. Complete Conversion Table of Mass Measurement Units
In Vietnam, we mainly use common mass measurement units such as Ton, Tạ, Yen, Kilogram, Gram, Miligram. Below is a complete conversion table of mass units encompassing all globally recognized units of measurement.

Guide to Reading the Conversion Table:
- Vertical Units: Reference values for measuring mass.
- Horizontal Units: Values converted across different units of mass (converted values)
- Example: First row: 1 Ton = 1 Ton = 10 Quintals = 100 Centals = 1000 Kilograms = 10,000 Hectograms = 100,000 Decigrams = 1,000,000 Grams = 10,000,000 Milligrams.

III. Guidelines for memorizing mass unit conversions
Looking at the conversion table above, you might find it very confusing and impossible to remember all the values, right? Don't worry, you still have a way to quickly convert units without having to remember too much. To memorize the mass unit conversions effectively, we need to remember the following:
- Memorize the order of mass units
- Follow the rule: Each reference unit will multiply by 10 to the right and divide by 10 to the left.
1. Sequence of mass units
According to the SI system, mass units are arranged in the following order, and you must memorize them even if they are not widely used in everyday life.
- Ton
- Quintal
- Cental
- Kilogram
- Hectogram
- Decagram
- Gram
- Milligram
When you want to convert mass units, it's advisable to list the units horizontally for easier viewing and conversion.
Tấn – Tạ – Yến – Kilogram – Hectogram – Decagram – Gram – Miligram |
2. Rule of converting mass units
As mentioned above, we have the following rule: “Each reference unit will multiply by 10 times the adjacent unit to the right and divide by 10 times the adjacent unit to the left.”
Example: If we take the unit Quintal as the reference unit, then 1 Quintal equals 10 Centals (10 times the adjacent unit to the right) and 1 Quintal equals 0.1 Ton (10 times smaller than the adjacent unit to the left).

Based on this conversion rule, you can convert all mass units worldwide. However, you need to pay attention to the following to avoid confusion.
- Identify the correct order and relationship between units to avoid confusion.
- Use a calculator to ensure accuracy and prevent errors.
IV. Some mass units of different countries around the world
In Vietnam, we use the international system of mass units in general, but some countries still use different mass units specifically. Although the mass units of other countries are less common, we should also learn about them to know more.
1. Mass units of the United Kingdom
- Pound (lb): The official unit of the British system, equivalent to about 0.453592 kg.
- Ounce (oz): 1 lb = 16 oz.
2. Mass units of the United States
- US Ton (short ton): 1 US ton = 2000 pounds = 907.1847 kg.
- US Hundredweight (cwt): 1 US cwt = 100 pounds = 45.35923 kg..
- US Quarter (qr): 1 US qr = 25 pounds = 11.33981 kg.
- US Stone: 1 US stone = 14 pounds = 6.350293 kg.
- Dram (dr): 1 dr = 1/256 ounces
- Grain (gr): 1 gr = 1/7000 pounds
3. Mass units of Austria
- Metzen: 1 metzen = 56.25 kg.
4. Mass units of Canada

V. Special mass units
Besides the common mass units, we have special mass units dedicated to specific objects such as diamonds, the Earth, nutrients, medications, etc.
1. Carat – Used in the gemstone industry
Cara hay Carat là đơn vị đo khối lượng sử dụng trong ngành đá quý, nó tương đương với 0,2 gram (200 miligram). |
2. Microgram – Used in pharmaceutical and nutritional fields
Ug stands for microgram (mcg), a unit of mass measurement in the International System of Units (SI), equivalent to one millionth of a gram (1 µg = 0.000001 g). This unit is commonly used to measure small amounts of nutrients and medications in functional foods and in the medical field.
3. M⊕ - Earth Mass Unit
In astronomical research, to measure the mass of other planets, Earth Mass (M⊕) is the equivalent mass unit of Earth. 1 M⊕ = 5.9722 × 1024 = 5.972E24 kg to describe the mass of other planets in the solar system.
