• ### Measurement of Weight (Conversion of weights)

• Measurement of Weight

Standard unit of weight is kilogram. We commonly use grams and kilograms to measure weight. Gram is the basic/standard unit of weight which is written as ‘g’. All units of weight are related to each other.

We measure small weights in cg and mg and large weights g and kg.

According to the weight conversion charts, units of weights and their equivalents are:

1 kilogram (kg) = 10 Hectograms (hg) = 1000 g

1 Hectogram (hg) = 10 Decagrams (dag) = 100 g

1 Decagram (dag) = 10 Grams (g)

1 Gram (g) = 10 Decigrams (dg) = 100 cg = 1000 mg

1 Decigram (dg) = 10 Centigrams (cg)

1 Decigram = 0.1 Gram

1 Centigram (cg) = 10 Milligrams (mg)

1 Centigram = 0.01 Gram

1 Milligram = 0.001 Gram

An easy way to remember the above conversion chart is the following statement:

Conversion

While converting from a larger unit to a smaller unit, we multiply

Example 1:

g mg

1 g = 1000 mg

Therefore, 3 g = 3 x 1000 = 3000 mg

Example 2:

kg g

1 kg = 1000 g

Therefore, 2.5 kg = 2.5 x 1000 = 2500 g

While converting from a smaller unit to a larger unit, we divide

Example 1:

g hg

1 g = 1/100 hg

Therefore, 20 g = 20/100 hg = 0.2 hg

Example 2:

g kg

1 g = 1/1000 kg

Therefore, 5g = 5/1000 kg = 0.005 kg
