Units of Mass
The fundemental unit for measuring mass is the gram.
There are also other units for measuring large and small quantities, the most common are:
| kilogram | kg | 1,000 g |
| hectogram | hg | 100 g |
| decagram | dag | 10 g |
| gram | g | 1 g |
| decigram | dg | 0.1 g |
| centigram | cg | 0.01 g |
| milligram | mg | 0.001 g |
Note that each unit is 10 times larger than the previous.
The problem of converting units to other units becomes an issue of multiplying or dividing the unit by one followed by as many zeros as there are places between them on the table above..
50 kg
dg.
In this case, multiply (because the kilogram is greater than the decigram) the unit by one followed by four zeros, since there are four places between both units.
50 kg · 10,000 = 500,000 dg
408 mg
dg
In this case, divide (because the milligram is smaller than the decigram) by one followed by two zeros, since there are two places between both units.
408 : 100 = 4.08 dg

Convert to grams:
5 kg 5 hm 7 dag
5,000 g + 500 g + 70 g = 5,570 g
3 g 2 cg 3 mg
3 g + 0.02 g + 0.003 g = 3.023 g
25.56 dag + 526.9 dg
255.6 g + 52.69 g = 308.29 g
53,600 mg + 9,830 cg
53.6 g + 98.3 g = 151.9 g
1.83 hg + 9.7 dag + 3,700 cg
183 g + 97 g + 37 g = 317 g
Other units of mass
Metric ton or tonne
It is used to measure very large masses.
1 t = 1,000 kg
Quintal metric
1 q = 100 kg
