The table of mass measurement units and how to convert mass measurement units will be introduced by Quantrimang.com in the article below, please refer to it.

1. What is the unit of mass?
A unit of mass is a unit used to weigh a specific object to help us know the mass of that object.
For example:
- Duong weighs 62kg.
- The bag of rice weighs 5 yen.
2. Table of mass measurement units
The table of mass units is arranged in order from largest to smallest:

Specifically, the units of mass are as follows:
- 1 ton = 10 quintals = 1000kg
- 1 quintal = 10 yen = 100kg
- 1 bird's nest = 10kg
- 1kg = 10hg = 1000g
- 1 hour = 10 days = 100g
- 1dag = 10g
3. How to convert units of mass
To be able to convert between units of mass, you need to understand the following rules:
Rule 1 : When converting a unit of mass from a larger unit to the next smaller unit, add 1 zero (multiply that number by 10) to that number. If there is a unit in the middle, add 2 zeros and if there are 2 units, add 3 zeros...
For example:
- 2 tons = 20 quintals = 200 yen = 2000 kg
- 9 kg = 90 hg = 900 dag = 9000g
Rule 2 : To convert a unit of mass from a smaller unit to the next larger unit, divide that number by 10 (or subtract 1 zero from that number), for every 1 unit, divide by 100 (subtract 2 zeros)...
For example:
- 5000g = 500dag = 50hg = 5kg
- 8000kg = 800 yen = 80 quintals = 8 tons

4. Example
Example 1. Convert units of mass
- 12 yen = 120kg (yen unit is right before kg unit so just take 12x10)
- 10 tons = 10,000,000g (ton is 5 units away from g so we have 10x1000,000)
- 100 quintals = 100,000 kilograms (quintal is 2 units away from kilograms so we have 100x1000)
- 2000g = 20hg (g is 1 unit away from hg so we have 2000/100)
Example 2 : Calculations with units of mass
If the units of measurement are the same, we perform calculations with mass, keeping the units the same. If the units of measurement are different, we must convert to the same units of measurement before performing calculations.
- 17kg + 3kg = 20kg
- 23kg + 123g = 23000g + 123g = 23123g
- 54kg x 2 = 108kg
- 1055g : 5 = 211g
- 6 quintals 4 swallows + 20 kg = 640kg + 20kg = 660kg
Example 3 : Comparison
Convert 60dag = 600g => 600g = 60dag
Convert 6kg = 6000g => 6kg <>
- 4 tons 3 quintals 5 yen and 4370 kg
Convert 4 tons = 4000kg
3 quintals = 300kg
5 bird's nest = 50kg
=> 4 tons 3 quintals 5 yen = 4350kg => 4 tons 3 quintals 5 yen < 4370="">
